Step-by-step explanation:

A fractional exponent can be written as a number with a radical to the power of the denominator raised to the power of the numerator.  It sounds difficult, but is really very easy.

$x^{\frac{4}{13} } =\sqrt[13]{x^{4} } \\x^{\frac{7}{3} } =\sqrt[3]{x^{7} }$

Thus, the answer is A
