The square root of a number is the number that when multiplied to itself gives the original number as the product. Finding the square root of a number is the inverse of squaring a number. 81 = a × a = a 2 Thus, a = √81= √ (9 × 9) 9 × 9 = 81 or -9 × -9 = 81. Therefore √81= ± 9 This shows that 81 is a perfect square.

For example, to find the square root of 30 with a precision of three numbers after the decimal point: Step 1: a = 30 is between 25 and 36, which have roots of 5 and 6 respectively. Let us start with b = 5.5. Step 2: e = a / b = 30 / 5.5 = 5.45 (45). Since b is not equal to e (5.500 ≠ 5.454), continue calculation.
