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

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.

Paul

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.

To enter the power of 10 with exponent use the Exp key followed by the exponent. If the exponent is negative, you must use the negation key (-) not the - key (for subtraction).

When you press the Exp key you do not type in the 10.

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.

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.

The problem is as follows:

3000 ( 1+ 0.06/360) exp.2520

Hello,

I dont think you got a lemon.

You acn always enter the powers of 10 as 10, [y^x], but is is less efficient than the EE key

This EE representation is a shortcut.

If you want 10 to the 5th power you just enter [2nd] [EE] 5 and the calculator displays 100000. Of course if you need any other number multiplying the power of ten you enter the following e.g. 2.677[x][2nd][EE]5.

You will not get any error with a positive exponent. But if your exponent is negative you should use the change signe key to the left of ENTER and symbolized by (-)

To avoid all errors I would use parentheses to enclose my exponent.

Here is how to explain the seemingly erroneous result

10 [EE] 5 ) (-) is interpreted by your calculator as 10x(10^(-5)) which evaluates correctly to 0.0001 because [EE] by itself stands for 10^ .

Hope it clarifies this point for you.

By the way some new calculators (Casio) don't have this EE key. Instead you find a key labeled x10^X .

Hope it helps
