Answer:

option D

3*(\sqrt{x}+\sqrt{x-3})

Step-by-step explanation:

Given in the question an expression,

\frac{9}{\sqrt{x} -\sqrt{x-3}}

Step 1

Divide and multiple by \sqrt{x}+\sqrt{x-3} to remove radical sign from denominator.

\frac{9}{\sqrt{x} -\sqrt{x-3}}*\frac{\sqrt{x} +\sqrt{x-3}}{\sqrt{x} +\sqrt{x-3}}

Step 2

Apply a² - b² = (a+b)(a-b)

\frac{9*\sqrt{x}+\sqrt{x-3}}{\sqrt{x^{2}}-\sqrt{(x-3)^{2}}}}

Step 3

\frac{9*\sqrt{x}+\sqrt{x-3}}{x-x+3}

Step 4

\frac{9*\sqrt{x}+\sqrt{x-3}}{3}

Step 5

3*(\sqrt{x}+\sqrt{x-3})
