Question

simplify one upon root 9 minus root 8

Answer 1

Hey dear!


Here is yr answer.....
$= > \frac{1}{ \sqrt{9} - \sqrt{8} } \\ \\ on \: rationalising......... \\ \\ = > \frac{1}{ \sqrt{9} - \sqrt{8} } \times \frac{ \sqrt{9} + \sqrt{8} }{ \sqrt{9} + \sqrt{8} } \\ \\ = > \frac{ \sqrt{9} + \sqrt{8} }{9 - 8} \\ \\ = > \sqrt{9} + \sqrt{8} \\ \\ = > 3 + \sqrt{8}$

Hope it hlpz...

Answer 2

hii!!

here's Ur answer...

$we \: have \: to \: rationalise \: \frac{1}{ \sqrt{9} - \sqrt{8} } \\ \\ = \frac{1}{ \sqrt{9} - \sqrt{8} } \times \frac{ \sqrt{9} + \sqrt{8} }{ \sqrt{9} + \sqrt{8} } \\ \\ = \frac{1( \sqrt{9} + \sqrt{8}) }{( \sqrt{9} - \sqrt{8} )( \sqrt{9} + \sqrt{8} ) } \\ \\ = \frac{1( \sqrt{9} + \sqrt{8} )}{ {( \sqrt{9} )}^{2} - {( \sqrt{8} ) }^{2} } \\ \\ = \frac{1( \sqrt{9} + \sqrt{8}) }{1} \\ \\ = \sqrt{9} + \sqrt{8} \\ \\ = 3 + \sqrt{8} \\ \\ hope \: this \: helps...$
