Answer
$\frac{\sqrt {65f}}{5}$
Work Step by Step
$\frac{\sqrt {13f^3}}{\sqrt {5f^2}}$
$\frac{\sqrt {13f^3}}{\sqrt {5f^2}}*\frac{\sqrt {5f^2}}{\sqrt {5f^2}}$
$\frac{\sqrt {65f^5}}{\sqrt {25f^4}}$
$\frac{\sqrt {65f^5}}{5f^2}$
$\frac{\sqrt {65f^2*f^2*f}}{5f^2}$
$\frac{f^2\sqrt {65f}}{5f^2}$
$\frac{\sqrt {65f}}{5}$
