Question

rationalize the denominator √7/√8+1​

Answer 1

$\frac{ \sqrt{7} }{ \sqrt{8} + 1} \times \frac{ \sqrt{8} - 1 }{ \sqrt{8} - 1 } \\ \\ = > \frac{ \sqrt{56} - \sqrt{7} }{ {( \sqrt{8} )}^{2} - {(1)}^{2} } \\ \\ = > \frac{2 \sqrt{14} - \sqrt{7} }{8 - 1} \\ \\ = > \frac{2 \sqrt{14} - \sqrt{7} }{7} = \frac{2 \sqrt{2} }{ \sqrt{7} } - \frac{1}{ \sqrt{7} }$
