The logarithmic expression of 4^(1/2) = 2 is 
<h3>How to rewrite the expression?</h3>
The expression is given as:
4^(1/2) = 2
Take the logarithm of both sides
log(4^(1/2)) = log(2)
Apply the change of base rule
1/2log(4) = log(2)
Divide both sides by log(4)
1/2 = log(2)/log(4)
Change the base

Rewrite as:

Hence, the logarithmic expression of 4^(1/2) = 2 is
