Square Root of 91 by Long Division Method
Step 1: Write 91 with pairs of zeros after the decimal point as 91.000000.
Step 2: Find a number that, when squared, gives 91 or less. 9 × 9 = 81, leaving a remainder of 10.
Step 3: Bring down the next pair of zeros. 1000 becomes the new dividend.
Step 4: Double the quotient. It is 18. Write 180 in the place of the new divisor.
Step 5: Find a number such that (180 + number) × number ≤ 1000. We determine that 180 + 5 = 185 and 184 × 5 = 920.
Step 6: Subtract 920 from 1000. The result is 80, and we bring down the next pair of zeros, making the new dividend 8000.
Step 7: Repeat the process until the approximation is accurate to 3 decimal places.
Thus, √91 ≈ 9.539.
