Answer
$\frac{x^{2}\sqrt 7}{5}$
Work Step by Step
Step 1: $\sqrt \frac{7x^{5}}{25x}$
Step 2: $\sqrt \frac{7x^{5-1}}{25}$
Step 3: $\sqrt \frac{7x^{4}}{25}$
Step 4: $\frac{\sqrt {7x^{4}}}{\sqrt {25}}$
Step 5: $\frac{\sqrt 7\times\sqrt {x^{4}}}{\sqrt {25}}$
Step 6: $\frac{\sqrt 7\times x^{2}}{5}$
Step 7: $\frac{x^{2}\sqrt 7}{5}$
