Question

Evaluate. Write your answer in fraction simple form.
(1/9)^2

Answer 1

Fraction potentiation

To calculate a fraction, it is almost the same as calculating a number normal to the power. The numerator and denominator of the fraction are multiplied as many times as possible indicated by its exponent, then:

`\boldsymbol{\sf{\left((1)/(9)\right)^(2)=(1*1)/(9*9)=\cfrac{1}{81} }}`

Therefore the fraction 1/81 is already in reduced form, so it is no longer possible to simplify it.
