What Is the Square Root of 144?

The square root of a number is the number (integer) which when multiplied by itself results in the original number.
144 = a × a = 122
Then a = √144 = √(12 × 12)
12 × 12 = 144 or -12 × -12 = 144.
The square root of 144 is +12 or -12.
This shows that 144 is a perfect square.
