Answer 2

$\huge\bold\mathfrac{ANSWER~:}$

$= \frac{15}{ \sqrt{10} + \sqrt{20} \sqrt{40} - \sqrt{5} - \sqrt{80} } \\ \\ = \frac{15}{ \sqrt{10} + 2 \sqrt{5} + 2 \sqrt{10} - \sqrt{5} - 4 \sqrt{5} } \\ \\ = \frac{15}{3 \sqrt{10} - 3 \sqrt{5} } \\ \\ = \frac{5}{ \sqrt{10} - \sqrt{5} }$

Here we have value of √5 = 2.236 and

√10 = 3.162.

$= \frac{15}{3.162 - 2.236} \\ \\ = \frac{15}{0.926} \\ \\ = 16.1987 \\ \\ \huge{\green{\ddot{\smile}}}$
