My book has these steps for evaluating a logarithmic equation and I don't quite understand what is going on. It says...

log (2) x(x-4)=5

x(x-4)=2^5 <---------> this is the level I am getting problems... how does log(2) divide the 5 on the other side and end up getting 2^5 ??

By the way this is how the equation continues( which I understand)

X^2-4x -32

(x-8)(x+4)= 0

x=8 x=-4
