Answer:

#1/2#

Explanation:

We have:

#sqrt(1/4)#

Using a simple observation, we got:

#=sqrt((1^2)/(2^2))#

Using the properties, #(a^b)/(c^b)=(a/c)^b#.

So, we got

#=sqrt((1/2)^2)#

#=+-1/2#

Since we are talking about real numbers, we will only take the principal (positive) square root, and so the answer will be just #1/2#.
