Question

rationalize the denominator of 3/root 5+ root 2

Answer 1

Answer:root5-root2

Step-by-step explanation:

3/(root 5+root 2)

By multiplying numerator and denominator with root5-root2

We get root5-root2 as ans

Answer 2

Step-by-step explanation:

By the given data  

$\frac{3}{\sqrt{5}+\sqrt{2} }$ Rationalizing the denominator

$\frac{3(\sqrt{5}-\sqrt{2} ) }{(\sqrt{5}+\sqrt{2})(\sqrt{5}-\sqrt{2}) }$    Multiplying and dividing with $\sqrt{5} -\sqrt{2}$ since it is the Rationalizing factor.

We get;

$\frac{3(\sqrt{5} -\sqrt{2} ) }{3}$

Therefore our final answer is $\sqrt{5} -\sqrt{2}$
