The answer is log 64 i know cuz im asain jk im just really good at math
Definitely not D, because one of the x's needs to be negative, and the other should be positive so the x will end up negative when it is multiplied.
I want to say the answer is C. (-x-2i) (x-2i)
Hope this helps :)
I'm assuming you meant to say a^3. If so, then
a^3 = a*a*a
a^3 = 5*5*5
a^3 = 125
