Q1 of 85 Page 138

Find the square roots of the following numbers by division method.

1089

Given, a number as 1089.

We need to find out the square root using division method


Step 1: Pair the given digit number, starting from units place to left as 10 and 89


Step 2: Find the largest number whose square is less than or equal to the first pair or single digit from left. Here we get 3 × 3 = 9



Step 3: Subtract the resulted value 9 from the number


Step 4 : Bring down the second pair 89 to the right of the remainder



Step 5: double the quotient 3



Step 6: Guess the possible value such that the product is equal to or less than new dividend



Hence, the square root of 1089 is 33
