In mathematics, a method for expressing powers and roots together is known as a fractional exponent.
Let's see the solution step by step.
Given: 4 to the power of 1/2 or 4(1/2)
First, rewrite 4 as 22
4(1/2) = 22(1/2)
Now, we will apply the rules of exponents, (am)n = amn.
Thus, we cancel the common factor of 2
21 = 2
