# I have a few questions. First, I want to multiply exponents like 5 to the 3rd x 5 to the 4th and not have it give me 78125. Can I set it do it gives me 5 to the 7th? I also want to know if I can factor on this calculator, if so, how? lastly, How do I find the GCD and LCM on this calculator?

What I need to know is if I can find the prime factorization of a composite number on this calculator, not the factorial, for example, the prime factorization of 4400 would be:
2⁴ x 5² x 11 (can I get an answer written out like this?).

Also, when I multiply something like 5² x 5³ = can I get an answer like 5² x 5³ = 5⁸ instead of 3125?

I was told I can not calculate the LCM or GCD using this model, is that true? Any way to simplify this process so I don't waste valuable time in a test doing factor trees?

No, this makes no sense to me and I am not sure you understnd the question I am asking, I need the answer to be written out exponentially, so.. (I don't have the keys to write this properly)I am looking for the answer to be in this format but not written out like this. The prime factorization of 4400 would be:
2 squared x 10 squared x 11

also, a calculation like 5 to the 3rd x 5 to the 4th is giving me 78125 instead of 5 to the seventh.

How do I set me calculator to give me answers in a exponential format?

Hi,

You should use the parenthesis to specify the order of operation, .

To insert paranthesis, follow the following steps

You do not need parentheses.To insert paranthesis..
Use Replay and [SHIFT] [INS] to add parentheses.
Blinking [ ] is the insert cursor.

Now you can specify the order of operation to get the desire result..

You can find the factor of a number using this calculator, but you can perform factorial for a number using this calucltor
Eg: Factorial of 4 is 4X3X2X1=24
To calculate this 4 SHIFT x! =

GCM and LCM cannot be caluculated with this model..

For the list of operation you can perform using this calculator and to know how to peform it, you can download the instruction manual from the below link

please leave me comment, if you need further assistance

As i said above you cant find factors, GCD and LCM..This is true..

Suppose if you want to perform 5+4 x 3+5, you should get 9 x 8 = 72

but calculator calculate it as 5 +12 +5 =22

So to solve this, youhave to add braces ( 5+4 ) x(3+5), so get the correct result

To add braces foloow these steps

Use Replay and [SHIFT] [INS] to add parentheses.
Blinking [ ] is the insert cursor

Please reconsider my solution and if you feel that its worth, Accept my solution and rate it good..

Else you can go with other solution..

Thanks using Fixya!

10 to the 4th is 10 X 10 X10 X10.

Ten multipled by itself four times equals ten thousand.

### What is most common power problem?

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents
Division with the same base - subtract the exponents
Exponent to an exponent - multiply the exponents
Negative exponent - 1 over the same number to the positive exponent
Zero exponent - anything to the exponent 0 is 1

Good luck,

### How do you simplify the exponent on the calculator?

Hi,

I assume 13m/2 is the radius of the sphere and you are trying to calculate the volume of the sphere.

The first thing we have to think of is BEDMAS, the order of operations, as some calculators do them correctly, while others do not. Let's be safe and do the BEDMAS manually so we know we will get the correct answer.

B - brackets - enter 13/2 in the calculator - hit enter
E - exponents - with the answer from the first line in the calculator, use the hat key (^) or the y to the x key to raise this to the third power (exponent 3).
M - multiply - with the answer from the line above, multiply this by pi or use what you are instructed to use or use 3.14159, then multiply by 4 and divide by 3.

Good luck.

### The exponent function automatically displays and multiplies by 10. How do I turn this off?

Here is the manual in PDF format. Simply search the documant once loaded by holding the "CTRL" key and pressing "F" this will bring up a search window. From there type in the search window "exponent" there are 6 different mentions of it. the 4th one gives you directions.
I hope this helps you.

### What is the answer to to this (x^5)^3(x^3)^4

We have to follow BEDMAS, the order of operations, where brackets are first, then exponents, followed by division and multiplication, and finally addition and subtraction.

Also, we have to use the exponent law of an exponent to an exponent, we multiply the exponents with the same base.

If we forget this, we can always do it the long way.

(x^5)^3 = (x^5)(x^5)(x^5) = x^15

Similarly, (x^3)^4= (x^3)(x^3)(x^3)(x^3) = x ^12

Now that we have done the exponents, we can multiply x^15 by x^12 and get x^27.

Good luck.

### How to calculate 40 raise to power 77 in fx -991

In two parts. 40^77 is a 124-digit number, too large for the calculator to handle. But you can calculate it by separating it into (4^77)*(10^77).

Calculating 4^77 gives about 2.28*10^46. 10^77 is just that, 10^77. To multiply the two together, simply add the exponents to get 2.28*10^123.

### I am trying to calculate powers with my Texas Instruments BA ii plus, but big powers such as ^360 gives me an error msg. How can I solve this problem? Thanks!

Break the problem up into smaller pieces.

There's a limit to how big a number the calculator can represent. Numbers as large as 10 times 10 to the 100 simply can't fit into the calculator. For really large numbers, calculate the mantissa and the exponent (power) separately.

For example, to calculate 2^360, first calculate 2^300: press 2 ^ 3 0 0 = and see 2.037036*10^90. Divide by 10^90 (and remember the 90): / 1 0 y^x 9 0 = and see 2.04. Multiply by 2^60: * 2 ^ 6 0 = and see 2.348543*10^18. Multiply that by the 10^90 we took out earlier by adding exponents and write down 2.348543*10^108. That number is too large to fit into the calculator but we got it by calculating the 2.348543 and the 108 separately.

Press 1 E 4

The E means "times 10 to the" so 1E4 is 1*10 to the 4th 10 to the 4th.

### Looking for a syntax

I am not sure what you are asking for?
Repeated multiplication (with same factor) is called raising a number (base) to a power. The exponent of the power is equal to the number of times the factor is repeated.
The calculator has several buttons to calculate powers.
For the square X*X you have a key [X^2].
For the cube X*X*X you MIGHT have a dedicated key [X^3].
However all calculators (scientific) have a universal power key marked [^] or [X^y] or [Y^x]

Example : In 5x5x5x5x5x5x5 you have a repeated multiplication, so the base is the factor (5) and the exponent is equal to 5. It is equal to the number of times the factor is repeated.
So 5x5x5x5x5x5x5 can be written much more efficiently as 5^7

Entering 5 then pressing the [^] key, followed by the exponent 7 gives the result 78125.
