Answer 1

Answer:

B 3x^ 3/4

Step-by-step explanation:

The fourth root can be written as the 1/4 power

3 * (x^3) ^ 1/4

a^b^c = a^ (b*c)

3 * (x)^ (3*1/4)

3 * x^ (3/4)

3 x^3/4

Answer 2

$\sqrt[n]{a^m}=a^{\frac{m}{n}}\\\\\text{We have}\ 3\sqrt[4]{x^3}=3x^{\frac{3}{4}}\\\\Answer:\ \boxed{B.\ 3x^{\frac{3}{4}}}$
