Answer 10

If that wasn't what you were looking for:
search for wolfram alpha on google
then search for type "(√7+√x) /(√7-√x)" simplified
it gives answer + explanation

Answer 11

\[\frac{√7+√x}{√7-√x}\]
\[=\frac{√7+√x}{√7-√x}\times1\]
rationalise the denominator , by multiplying by it's irrational conjugate
( the irrational conjugate of \(\sqrt 7-\sqrt x\) is \(\sqrt 7+\sqrt x\) )

\[=\frac{√7+√x}{√7-√x}\times\frac{\sqrt 7+\sqrt x}{\sqrt 7+\sqrt x}\]

Answer 12

\[=\frac{(√7+√x)(\sqrt 7+\sqrt x))}{(√7-√x)(\sqrt 7+\sqrt x)}\]
the denominator simplifies to become a rational

\[=\frac{(√7+√x)(\sqrt 7+\sqrt x))}{7-x}\]

and the numerator simplifies

\[=\frac{(√7+√x)^2}{7-x}\]
