Question

What index of y make value 1/y^2

Answer 1

Answer:

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

Step-by-step 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,

$\dfrac{1}{a^x}=a^{-x}$

So, the given expression is :

$\dfrac{1}{y^2}=y^{-2}$

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