How do you know if a square root can be simplified?
Simplifying a square root isn’t as hard as it looks. To simplify a square root, you just have to factor the number and pull the roots of any perfect squares you find out of the radical sign….For example, let’s simplify √72:
- √72 = √(9 x 8)
- √72 = √(9 x 4 x 2)
- √72 = √(9) x √(4) x √(2)
- √72 = 3 x 2 x √2.
- √72 = 6√2.
