How do you find the root value?

The product property of square roots states that for any given numbers a and b, Sqrt(a × b) = Sqrt(a) × Sqrt(b). Because of this property, we can now take the square roots of our perfect square factors and multiply them together to get our answer. In our example, we would take the square roots of 25 and 16.

How do you find the positive square root?

A square root of a number b is the solution of the equation x2=b . It is a number that when multiplied by itself gives you b . Every positive number b has two square roots , denoted √b and −√b . The principal square root of b is the positive square root, denoted √b .

What is the positive square root of 121?
