Question

Which expression is equivalent to

A) z^10/y^10
B) y^10/z^10
C) z^20/y^20
D) y^20/z^20

Answer 1

The answer is D

Can you please have to simplify the expression
Then you express with a positive
To raise a fraction to a power, raise the numerator and denominator to that power
And then you will get your solution, which is D. Hope this helps

Answer 2

`{( \frac{ {y}^( - 2) {z}^(7) }{ {z}^( - 3) {y}^(8) } )}^( - 2) = {( {y}^( - 10) {z}^(10)) }^( - 2) = {( \frac{ {z}^(10) }{ {y}^(10) } )}^( - 2) = {( \frac{ {y}^(10) }{ {z}^(10) } )}^(2) = \frac{ {y}^(20) }{ {z}^(20) }`

The correct answer is D.
