Let's start by taking a look at an example evaluating the square root of $\greenD{25}$:
$\large \sqrt{\greenD{25}} = ,?$
Step 1: Ask, "What number squared equals $\greenD{25}$?"
Step 2: Notice that $\blueD5$ squared equals $\greenD{25}$.
$\large \blueD5^2= \blueD5 \times \blueD5 = \greenD{25}$
The answer
$\large \sqrt{\greenD{25}} = \blueD5$
