# 2log10(10x) Watch

1. why can 2log10(10x) not be written as log10(10x) + log10(10x)? log10 means log in base 10

EDIT: think i misread the question, i started off with log10 (10x^2), this cannot be written as 2log10(10x) can it as its not the whole of (10x) squared? in this case all I need to do is split it into log10(10) + log10(x^2)?
