Question 47755
log squared 1/8=-3

"log squared" sound mighty peculiar.
Are you sure it's not (base 2)
or maybe the (1/8) is squared.

I think it is probably base2.
Assuming it is the problem goes like this:

log(base2)(1/8)=-3
2^(-3)=1/8
2^(-3)=2^(-3)

A mysterious problem.  I suggest you check it out again.
