Question

The simplest rationalising factor of \[\sqrt{3} + \sqrt{5}\] is 

Options

• \[\sqrt{3} - 5\]

• \[3 - \sqrt{5}\]

• \[\sqrt{3} - \sqrt{5}\]

• \[\sqrt{3} + \sqrt{5}\]

Answer 1

We know that rationalization factor for `sqrta +sqrtb ` is . `sqrta -sqrtb` Hence rationalization factor of `sqrt3 +sqrt5`.
