SOLUTION

We are asked true or false if


(1)/(i^3)=(1)/(i^7)

Now


i=\sqrt[]{-1}

So,


\begin{gathered} (\sqrt[]{-1})^3=\sqrt[]{-1} \\ \\ \text{also } \\ \\ \sqrt[]{-1})^7=\sqrt[]{-1} \end{gathered}

So the statement is true.

Note that since the powers or indices are odd numbers, it would be the same
