Solution:
From the laws of exponents,
[tex]a^{\frac{1}{n}}=\sqrt[n]{a}[/tex]Thus, when you raise a number to the power with the exponent 1/2, let the number be a.
This implies
[tex]a^{\frac{1}{2}}=\sqrt{a}[/tex]Hence, when you raise a number to the power with the exponent 1/2, you get its square root.
The correct option is B
