How to solve this
please tell me fast​

Answer 1

Answer:

$\sqrt{9} + \sqrt{8} .$

Step-by-step explanation:

$\frac{1}{ \sqrt{9} - \sqrt{8} } \times \frac{ \sqrt{9} + \sqrt{8} }{ \sqrt{9} + \sqrt{8} } \\ \\ \frac{ \sqrt{9} + \sqrt{8} }{ \sqrt{9} \times \sqrt{9} - \sqrt{8} \times \sqrt{8} } \\ \\ \frac{ \sqrt{9} + \sqrt{8} }{9 - 8} \\ \\ \frac{ \sqrt{9} + \sqrt{8} }{1} \\ \\ \sqrt{9} + \sqrt{8} .$

hopefully its helped u dear :)
