Use the change of base formula.

$\normalsize\color{blue}{ \log_{32}4 =\log_{32}2^2 =2\log_{32}2=2\log_{32}32^{1/5}=}$

$\normalsize\color{blue}{ 2\log_{32}32^{1/5}= (1/5)(2)\log_{32}32=(2/5)\log_{32}32}$

This is not the final answer

solomonzelman · Answer

You got to know how to reduce it. If you can't, then I won't reduce it for you, since you are talking a test. I am not violating more than what I already did.
