Question

Rationalize the denominator
$\huge \red{\frac{25}{ \sqrt{40} - \sqrt{80} } }$
​

Answer 1

${\frac{25}{ \sqrt{40} - \sqrt{80} } } = {\frac{25}{2\sqrt{10} - 4 \sqrt{5} }} \\ \frac{25}{ \sqrt{4 \times5 } - \sqrt{16 \times 5} } = \frac{25}{ 2\sqrt{10} - 4 \sqrt{10} } \\ \frac{25}{2 \sqrt{10} - 4 \sqrt{5} } = \frac{25}{2 \sqrt{10} - 4 \sqrt{5} }$
