Question

$3\sqrt{5}+2\sqrt{7}+\sqrt{7}+\frac{1}{3}+\sqrt{5}+\frac{1}{10}$

Answer 1

$3\sqrt{5}+2\sqrt{7}+\sqrt{7}+\frac{1}{3}+\sqrt{5}+\frac{1}{10} = \\ \\ (3 \sqrt{5} + \sqrt{5})+(2 \sqrt{7}+ \sqrt{7} )+( \frac{1}{3}+ \frac{1}{10}) = \\ \\ 4 \sqrt{5}+3 \sqrt{7}+ \frac{1(30:3)+1(30:10)}{30} = \\ \\\boxed{ \boxed{4 \sqrt{5}+ 3\sqrt{7}+ \frac{13}{30} }}$
