Question

rationalise the denominators 3√5-√3/√5-√3 solution

Answer 1

Hey dear!


Here is yr answer.....


$= > \frac{3 \sqrt{5} - \sqrt{3} }{ \sqrt{5} - \sqrt{3} } \\ \\ = > \frac{3 \sqrt{5} - \sqrt{3} }{ \sqrt{5} - \sqrt{3} } \times \frac{ \sqrt{5} + \sqrt{3} }{ \sqrt{5} + \sqrt{3} } \\ \\ = > \frac{15 + 3 \sqrt{15} - 1\sqrt{15} - 3}{5 - 3} \\ \\ = > \frac{12 + 2 \sqrt{15} }{2} \\ \\ = > \frac{2(6 + \sqrt{15} )}{2} \\ \\ = > 6 + \sqrt{15}$

Hope it hlpz....
