1. The problem statement, all variables and given/known data
log2√x

2. Relevant equations

3. The attempt at a solution

I thought that it might be something like log2x - log2x but thats not right. The book examples don't have any radicals.

Write √x with a fractional exponent.

That makes a lot more sense... So is it 1/2(log2x) or (log2x)/2(log2x)

$log(a^b) = b \cdot log(a)$

Why would you even consider that $log_2(\sqrt{x})= 1/2$ for all x?
