Answer 2

Hello friend
------------------

Thanks for your question.

=) In example

$\sqrt{7 } - \frac{3}{5} \sqrt{7} + 2 \sqrt{7 } \\ = 1 - \frac{3}{5} + 2 \sqrt{7 } \\ \\ = \frac{1}{1} \times \frac{5}{5} - \frac{3}{5} \times \frac{1}{1} + \frac{2}{1} \ \times \frac{5}{5} \sqrt{7} \\ \\ = \frac{5 - 3 + 10}{5} \sqrt{7} \\ \\ = \frac{12}{5} \sqrt{7}$
I hope this will helps you.

Thanks
