Question

Write the following in exponential form :

$a\times a\times a\times ........taken15times$

Answer 1

We have the expanded form as :

$a\times a\times a\times ........taken15times$

Conversion into exponential form :

We know that

$\mathit{a}\mathbf{}\mathbf{\times }\mathit{a}\mathbf{}\mathbf{\times }\mathit{a}\mathbf{}\mathbf{\times }\mathit{a}\mathbf{}\mathbf{\times }\mathit{a}\mathbf{}\mathbf{\times }\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{.}\mathbf{}\mathit{n}\mathbf{}\mathit{t}\mathit{i}\mathit{m}\mathit{e}\mathit{s}\mathbf{}\mathbf{=}{\mathit{a}}^{\mathbf{n}}$

So

$a\times a\times a\times ........taken15times=a^{15}$
