What is exponents and powers?

Exponent refers to the number of times a number is used in a multiplication. Power can be defined as a number being multiplied by itself a specific number of times. Exponent is the number to which a number is raised so as to define its power as a whole expression.

Given: $3^{-2}$

Now evaluate this we have to use

$x^{-2}$= 1/x²

So,

$3^{-2}$ =1/3²

$3^{-2}$ =1/9

Hence, the evaluate form is 1/9.
