log 4 (16)=2, because 4^2=16
log (1/2) of 32= -5, because 2(-1)^(-5)=2^5 or 32
ln e^3=3, because ln and e annihilate each other.

Solve the following: No decimals
A) log(base 4)(16)= log2(16)/log2(4) = 4/2 = 2
-------
B) log(base 1/2)(32)= log2(32)/log2(1/2) = 5/-1 = -5
--------
C) ln (e^3)= 3
------------
