i'm stuck on this problem. I have no clue how to start it. "If ab = 5, evaluate $log5a^2b^2$ sorry i dont know how to subscribt the 5.
so its log base 5 a ^ 2 b ^ 2.
help will be greatly appreciated!

Using the power law

$\log_{5}((ab)^2)= 2 \log_{5}(ab)$

then sub ab = 5

$\Rightarrow 2 \log_{5}(5)$

and finish
