ANSWER
[tex] \sqrt{60} [/tex]
EXPLANATION
The given exponentiial expression is
[tex] {60}^{ \frac{1}{2} } [/tex]
Recall that
[tex] {a}^{ \frac{1}{n} } = \sqrt[n]{a} [/tex]
A special case of this rule is when n=2.
Then,
[tex] {a}^{ \frac{1}{n} } = \sqrt{a} [/tex]
This implies that
[tex]{60}^{ \frac{1}{2} } = \sqrt{60} [/tex]
The correct answer is B.
