Question

.

Answer 1

Use
\[ \frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}} \]
and then simplify the fraction using normal rules.

Answer 2

? confused...

Answer 3

\[ \frac{\sqrt{\frac{42w^3}{45p^3}}}{\sqrt{\frac{39x^2w}{70p^2}}}=\sqrt{\frac{\frac{42w^3}{45p^3}}{\frac{39x^2w}{70p^2}}} \]

Answer 4

The problem is... I don't get how to solve radicals.. at all... :(

Answer 5

Now you can just ignore the root sign and simplify the fraction inside,
\[ \sqrt{\frac{\frac{42w^3}{45p^3}}{\frac{39x^2w}{70p^2}}}=\sqrt{\frac{42w^3*70p^2}{45p^3*39x^2w}} \]
Try to do the last few steps.
