how to find square root? |
The root of a number is an equal factor of the number. For example, find the root of 16 First, we need to factor 16 16 = 1 × 16 16 = 2 × 8 16 = 4 × 4 The root of 16 is 4 because 4 is the equal factor for 16. We call 4 the square root of 16. 4 is called square root because we have to square 4 or raise 4 to a power of 2 to get 16 |
