Help with radical logs. $\log_ 2\sqrt{32}$ I am having trouble understanding logarithms. Specifically I can't understand this equation.
$$\log_2{\sqrt{32}}$$ 
I know the answer is $\left(\frac{5}{2}\right)$ but I don't know how it is the answer. If somebody could please explain the process step by step for solving this log and perhaps give examples of other radical logs I would really appreciate it.

Hint : $$\large \sqrt{32}=32^{\frac{1}{2}}=2^{\frac{5}{2}}$$
