Question

1/√23+5 whats the answer its from nuber system class 9

Answer 1

Answer:

The answer will be $\frac{ - \sqrt{ 23} + 5}{2}$

Step-by-step explanation:

$\frac{1}{ \sqrt{23} + 5}$

$\frac{\sqrt{23} - 5}{( \sqrt{23} + 5)( \sqrt{23} - 5) } \: \: \: (by \: rationalising \: the \: denominator)$

$\frac{ \sqrt{23} - 5 }{ \sqrt({23})^{2} - {5}^{2} }$

$\frac{\sqrt{23} - 5}{23 - 25}$

$\frac{\sqrt{23} - 5}{ - 2}$

$\frac{ - \sqrt{ 23} + 5}{2}$
