To Find:

We have to Find: The value of the equation.

Solution:

According to the problem, multiplying and dividing the equation with

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

we get,

$\frac{2( \sqrt{35} - \sqrt{21}) }{5 - 3} \\ \frac{2( \sqrt{35} - \sqrt{21}) }{2} \\( \sqrt{35} - \sqrt{21})$

Final Answer: The Correct answer is

$( \sqrt{35} - \sqrt{21})$
