Answer 15

Ah, exponent rules. When you have something like:
4^2 times 4^3

It is the same as 4^(2+3)

Let me find you an example.

Answer 16

So attempt it again and tell me what your answer is.

Answer 17

oh okay thanks. i see they have different rules for each one

Answer 18

but none of them look like my example

Answer 19

The first rule. ^^

Answer 20

If you re-arrange your question, you have:

(W^8) x (W^10) x (X^4) x (X^5)

Answer 21

ohhh! lol

Answer 22

thanks ;D

Answer 23

w^80xw^20? lool

Answer 24

Haha, what? No I think you're confusing something. What's the answer you're coming up with?

Answer 25

That's incorrect! See that would be right if it was (W^8)^10 and (X^5)^4

Answer 26

aww dammit...

Answer 27

You have the same base with different exponents being multiplied together. Check those exponent laws again.
