\)

Answer 6

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

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

Answer 7

This is not the final answer

Answer 8

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.

Answer 9

\( \Large \log_{32}4 = \frac{\log_{2}4}{\log_{2}32 } = \frac{?}{?}\)
