Question

which is the rationalized form of the expression the square root of x divided by the square root of x +the square root of 7

Answer 1

Answer:

I assume your goal is to rationalize the denominator -

So you need to multiply the denominator by its conjugate.

So we have:

$\frac{\sqrt{x} }{\sqrt{x}-\sqrt{7} } *\frac{\sqrt{x} +\sqrt{7} }{\sqrt{x} +\sqrt{7}}$

->

$\frac{x-\sqrt{7}\sqrt{x} }{x-7}$
