Question

Find the two square roots of the number 25

Answer 1

± 1/2 (or ± 0.5)

Here's how I would do it:
0.25 = 25/100

√0.25 = √(25/100)
= √25/√100
= ± 5/10
= ± 1/2

You have to remember that there are two square roots to a number; the primary (positive) root, and the secondary (negative) root. So be sure to include the ± sign.

Answer:
-1/2 and 1/2

Answer 2

One of the square roots is 5 and another is -5 (tell me if its right if you can)
