A power is a shortcut for a reapeated multiplcation. 6^4=6*6*6*6,
Ob scientific calculators there is aspecial key to enter powers. The key is usually marked Y^x or X^y or just a caret ^.
If the marking is on top of the key you press the key, if the marking on the face of the calculator, you press 2nd, or 2ndF or SHIFT followed by the key near which the marking is.

SOURCE: i don't know how to multiply by a negative

Press [2nd][,] to activate (EE) which appears on screen as a lower case E, enter the change sign (-) right of the [dot] on the bottom row of keys, enter the value of the exponent.
Ex: Enter Avogadro's number of Generalk Chemistry fame
6.02[SHIFT][,] (EE) (-)23
Here is screen capture of what it will look like.

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,

Paul

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.

You should have your answer.

Good luck.

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.

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.

Try to multiply (20x10-9) (1x10-9)


If you use the exponent rules you do not need to use a
calculator for this particular case. Anyway to enter power of 10 exponents you use the [EE] key. See screen capture below.

20 [EE] (+ -)9 [X] 1[EE] (+ -) 9

How do i do exponents on here other than to the second power


You press the EXP key and then enter the "POWER TO" digit... so you want say 8 Exponent 3, so you tap 8 the multiply key, & then the EXP key & then the number 3, & so on... so.... 8 x exp 3 OK?

How do I add Exponents on my T1-30xa calculater


Hello,
There is a rule of Algebra, that says
(a^m)[x] (a^n) = a^(m+n)

a is the base of the power, n, and m are the exponents. As you can see, multiplying two powers of the same base is equal to the power of the (common) base with the sum of the exponents.
If that is what you had in mind, the calculator uses the rule correctly and no intervention from you is necessary.
If you enter (2^4)[x](2^6), the calculator will give 1024, which is 2^10.

I may be wrong, but what you call add exponents refers really to performing addition where addends (the terms you add) are arbitrary powers, such as
2^7 + (5.5^3) - (1/3)^4

Once you enter a power term, the calculator calculates it and the result is now just a number. It can be added, subtracted, multiplied

For the exemple above
2 [Y to the x] 7 + (5.5)[Y to the x] 3 -(1/3) [Y to the x] 4 [=] yields 294.3626543

For the cube of 5.5 you can use the key combination [2nd][X^3]

Hope it helps.

Multiplying exponential numbers


I am needing to find out what key I can push for an exponent. I have an exponent that is 2520 and I dont know what button to push for it.

The problem is as follows:

3000 ( 1+ 0.06/360) exp.2520

3000 ( 1.000166667) exp. 2520

3000 - 4565.72

Final Answer
1565.72

Now how in the world did they get 4565.72. What buttons am I needing to push.
