Answer
$\frac{8\sqrt {x}}{3x}$
Work Step by Step
$\frac{2\sqrt {16}}{\sqrt {9x}}\times\frac{\sqrt {9x}}{\sqrt {9x}}$
=$\frac{2\sqrt {16}\times\sqrt {9x}}{\sqrt {9x}\times\sqrt {9x}}$
=$\frac{2(4)\times 3\sqrt {x}}{3\sqrt {x}\times 3\sqrt {x}}$
=$\frac{8\times 3\sqrt {x}}{9x}$
=$\frac{8\times \sqrt {x}}{3x}$
=$\frac{8\sqrt {x}}{3x}$
