WebMay 25, 2016 · Lets start with y = 2 log 2 ( x) which is the same as saying y = log 2 ( x) + log 2 ( x) . Since both side are equal if we do the same thing to them they will remain equal. So we can both both sides on top of 2. 2 y = 2 ( log 2 ( x) + log 2 ( x)) Since a b ∗ a c = a ( b + c) we can use that to expand it out. 2 y = 2 log 2 ( x) 2 log 2 ( x))
