Examples- 4x4=16 so the Square Root of 16 is 4. 5x5=25 so the square root of 25 is 5. In general and more precisely, we say that r is the square root of a number m, if r2 â¦ =m. If r is positive, it is the principal square root. For example, both 4 and -4 when squared equal 16, but 4 is the principal square root.
