We can rewrite as

$\sqrt{\frac{4}{100}} = \frac{\sqrt{4}}{\sqrt{100}} = \frac{2}{10} = \frac{1}{5}$

Hopefully this helps!

$0.2$

#### Explanation:

Another approach is to change to standard form,providing the power of 10 is even

$0.04 = 4 \times {10}^{- 2}$

:. sqrt0.04=sqrt(4xx10^(-2)

$\sqrt{4} \times \sqrt{{10}^{- 2}}$

$= 2 \times {10}^{- 1}$

$= 0.2$
