Question

Simplify

Answer 1

\[(\frac{ 7x^-2y }{ x^8y-5})^3\]

Answer 2

And?

Answer 3

Ah. Simplify. OK. Then you need to get things factored so they can cancel.

Answer 4

I started this today im confused i have no idea what to do ;-; do i distribute the 3?

Answer 5

Here is the question written correctly in latex :P

\(\Large(\frac{ 7x^{-2}y }{ x^{8}y^{-5}})^3\)

Answer 6

im not a LaTex genius :P

Answer 7

Well first off

\(\Large a^x \times a^y = a^{x+y}\)

\(\Large a^{-x}=\frac{1}{a^x}\)

\(\Large\frac{a^b}{a^c}=a^{b-c}\)

Answer 8

so i do distribute?

Answer 9

If the whole thing is ^3, that does not matter at the moment.

Though, I think we are not seeing the question quite as asked...

Answer 10

Well first lets use the second formula and simplify \(\ x^{-2}\) and the \(y^{-5}\)

We will at the end then do the ^3

Answer 11

If it is as TSP says, then yah, all you need are those rules.

Answer 12

TSP xD um...so i x^-2+8?

Answer 13

Yup!

And what is -2+8=?

And remember this value is going to be in the denominator.

Answer 14

ok nvm i have it thanks!! :D

Answer 15

Np then :)
