Question

please give me the long division steps to get the square root of 171

Answer 1

Plz refer to the image.. Steps ---
Step 1: Place a bar over every pair of digits starting from the unit digit. If the number of digits in it is odd, then the left-most single digit too will have a bar.Thus we have, 171.So 1st bar is on 71 and 2nd bar is on 1.

Step 2 : Find the largest number whose square is less than or equal to the 1st number,here it is '1'.

Step 3: Bring down the number under the next bar (i.e., 71 in this case) to the right of the remainder.

Step 4 : Add the divisor 1 and quotient 1 that gives us 2.

Step 5 : Think of a largest number in fill in the blank in such a way that the product of a new divisor and this digit is equal to or less than 71(new dividend). In this case 23 ×3 = 69.

Step 6 : Continue the same pattern (Add zeros as required)
