${\huge{\blue{\bold{\underline{Given:-}}}}}$

$\implies \frac{ \sqrt{x} }{ \sqrt{5} } = \sqrt{2} + 1 \\ \\ \implies \sqrt{x} = \sqrt{5}( \sqrt{2} + 1) \\ \\ \implies \sqrt{x} = \sqrt{10} + \sqrt{5} \\ \\ \implies( \sqrt{x}) {}^{2} = ( \sqrt{10} + \sqrt{5}) {}^{2} \\ \\ \implies \: x = \sqrt{10} {}^{2} + \sqrt{5} {}^{2} + 2 \sqrt{50} \\ \\ \implies \: x = 15 + 2 \sqrt{50}$

☆ The answer can also be 15+10root2.

Because root50 = 5root2
