Question

PLEASE HELP!

Answer 1

anything to the power of 0 is 1

Answer 2

that's a powerful hint right there

Answer 3

and anything to power of -1 flips

Answer 4

Is B the correct answer?

Answer 5

1. since the first paranthesis is to the power of "0", its value is "1" aand can be ignored.
2. check the power of "x" in the two paranthesis
\(\left(1\over x^5\right)^{-1}=x^5\)
so, x^5 should be on the numerator. so, we narrow down our options to B and D
3. notice that they have the same power for "z". so, lets check for the powers of "y" in both the paranthesis

Answer 6

@electrokid would B be correct?

Answer 7

did you sum up the powers of "y"?

Answer 8

It is D!!! because the sums of y are 3, right?

Answer 9

@electrokid

Answer 10

Answer 12
