Question

Simplify: 4/7√147 + 3/8√192 - 1/5 √75 with steps please​

Answer 1

You can write root 147 as $\sqrt{3 X 7 X 7}$ , root 192 as $\sqrt{8 X 8 X 3}$  and Root 75 as $\sqrt{3 X 5 X 5}$

So,

$\frac{4}{7} X 7 \sqrt{3} + \frac{3}{8} X 8 X \sqrt{3} - \frac{1}{5} X 5 X \sqrt{3} \\\\4\sqrt{3} + 3\sqrt{3} -\sqrt{3} \\\\6\sqrt{3}$
