[tex]8\sqrt{8}[/tex] can be written in the form [tex]8^{k}[/tex](adsbygoogle = window.adsbygoogle || []).push({});

Find the value of k

I'm positive is a really easy question I though that k = 1/8, but that is wrong.

What is the method to answer this question.. I used trial and error and got k = 3/2, but what is the proper way?

Thanks
