Question

rationalize the denominator 2/√7+√5

Answer 1

Answer:multiply numerator and denominator with √7-√5.

Then u will get √7-√5 as your answer

Step-by-step explanation:

Answer 2

After rationalizing we get  √7 - √5

Given equation is,

        $\frac{2}{\sqrt7+\sqrt5}$

Multiplying and Dividing the given expression by $\sqrt7-\sqrt5$

$\frac{2}{\sqrt7+\sqrt5}$  =  $\frac{2}{\sqrt7+\sqrt5}$ × $\frac{\sqrt7-\sqrt5}{\sqrt7-\sqrt5}$

           =  $\frac{2(\sqrt7-\sqrt5)}{7-5}$

cancelling 2 from numerator and denominator

           =  $\frac{2(\sqrt7-\sqrt5)}{2}$

           =  √7 - √5

    $\frac{2}{\sqrt7+\sqrt5}$  =  √7 - √5   is the solution.
