Hii friend,

=> 1/✓7 - ✓6 × ✓7+✓6/✓7+✓6

=> 1(✓7+✓6)/(✓7-✓6)(✓7+✓6)

=> (✓7+✓6)/(✓7)² - (✓6)²

=> ✓7 + ✓6 / 7-6

=> ✓7 + ✓6/1

=> ✓7+✓6....Ans...

$\frac{1}{ \sqrt{7} - \sqrt{6} }$



$\frac{1}{ \sqrt{7} - \sqrt{6} } \times \frac{ \sqrt{7} + \sqrt{6} }{ \sqrt{7} + \sqrt{6} }$



$\frac{ \sqrt{7} + \sqrt{6} }{1}$


=>
$\sqrt{7} + \sqrt{6}$




Hope it helps you
