what is $sqrt{0.04}$? write your answer as a decimal.

Explanation:

Step1: Recall square - root concept

We know that if $x^2 = a$, then $\sqrt{a}=x$ (for $a\geq0$). We need to find a number $x$ such that $x^2 = 0.04$.

Step2: Calculate the square - root

Since $0.2\times0.2 = 0.04$, then $\sqrt{0.04}=0.2$.

Answer:

$0.2$
