# Question: i really need someone to explain this step to me...

###### Question details

I really need someone to explain this step to me. Every formula
I can find makes my answer come out to be
10log(1-10x)-10log(**10**x) and NOT
10log(1-10x)-10log(x). No matter what I try I can't figure out how
to reconcile this unexplained multiple of 10 and both resources I
have to check my solution just skips over that part exactly like
Wolfram-Alpha does (picture). **log refers to the natural logarithm
(ln)**
