Question

What index of y make value 1/y^2

Answer 1

(-2) is the index of y make value 1/y².

Explanation:

We need to find what index of y makes value 1/y².

Here, the numerator is 1 and the denominator is y².

We know that,

`(1)/(a^x)=a^(-x)`

So, the given expression is :

`(1)/(y^2)=y^(-2)`

Hence, (-2) is the index of y make value 1/y².
