How do you complete a square root problem?

Just as subtraction is the inverse operation of addition and division is the inverse operation of multiplication, the square root operation is the inverse of the squaring operation.

Algebraically, you can see the analogues between operations and their inverses:

Addition solves problems like 6 + 7 = x, while subtraction solves problems like 6 + x = 7

Multiplication solves problems like 7 * 5 = x, while division solves problems like 5x = 7

Squaring solves problems like 2^2 = x, while square rooting solves problems like x^2 = 2

Say our problem was the square root of 4. You would look for what two numbers multiplied by themselves would equal that number. We know 2 multipled by 2 is equal to 4. (Aka 2^2).

Hope this helps.
