Question

Write ${\left(ab\right)}^4$ in the expanded form.

Answer 1

Expanded form

As the exponent of $ab$ is $4$, so $ab$ is multiplied by itself four times.

${\left(ab\right)}^4$$=ab\times ab\times ab\times ab$

Therefore, the expanded form of ${\left(ab\right)}^4$ is $ab\times ab\times ab\times ab$.
