ANSWER
The correct answer is D.
EXPLANATION
The given exponentiial expression is
[tex] {5}^{ \frac{7}{3} } [/tex]
Recall that:
[tex] {a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} } [/tex]
We put a=5, n=3 and m=7
This implies that,
[tex]{5}^{ \frac{7}{3} } = \sqrt[3]{ {5}^{7} } [/tex]
The correct answer is D.
The last option is correct.
