Question

the value of 2/√5 -√3 is? for class 9​

Answer 1

Answer :

$=\frac{2}{\sqrt{5}-\sqrt{3}} \\\\ rationalising \ factor=\sqrt{5}+\sqrt{3} \\\\ = \frac{2}{\sqrt{5}-\sqrt{3}} \times \frac{\sqrt{5}+\sqrt{3}}{\sqrt{5}+\sqrt{3}} \\\\ = \frac{2(\sqrt{5}+\sqrt{3})}{(\sqrt{5}-\sqrt{3})(\sqrt{5}+\sqrt{3})} \\\\ = \frac{2(\sqrt{5}+\sqrt{3})}{\sqrt{5}^2-\sqrt{3}^2} \\\\ =\frac{2(\sqrt{5}+\sqrt{3})}{5-3} \\\\ =\frac{2(\sqrt{5}+\sqrt{3})}{2} \\\\ =\sqrt{5}+\sqrt{3}$
