Answer:
[tex]2\sqrt{x}[/tex]
Step-by-step explanation:
Fractional exponents always mean roots. The denominator indicates which root it is. Since the denominator here is 2, the root is a square, so:
[tex](4x)^{1/2}=\sqrt{4x} =2\sqrt{x}[/tex]
Thus, the answer is [tex]2\sqrt{x}[/tex].
Hope this helps!
