Question

Write the exponent and the base in each of the following expressions :

${\left(\frac{-a}{b}\right)}^4$

Answer 1

The given expression compare with exponential form :- ${\left(a\right)}^n$ $\to$$a$ is the base and $n$ is the exponent .

Hence, the base $=\left(\frac{-a}{b}\right)$

and the exponent $=4$
