Best ResponseYou've already chosen the best response.0why do this? because you will take advantage of the fact that (ab)(a+b) = a^2  b^2 squaring the square root will cancel out the square root eg: \[\Large (\sqrt{x})^2 = x\] where is nonnegative

Best ResponseYou've already chosen the best response.0you didn't make a mistake @madhu.mukherjee.946 \[\Large \frac{1}{\sqrt{x}+\sqrt{y}} = \frac{\sqrt{x}\sqrt{y}}{xy}\] is true assuming \(\Large x \ne y\) and neither x nor y are zero
