32. Find the square root of 1471369.
A. 1210
B. 1213
C. 1313
D. None of these
Answer:
Option : B
In the given number, mark off the digits in pairs starting from the unit's digit.
Each pair and the remaining one digit is called a period.
Now, 12 = 1. On subtracting, we get 0 as remainder.
Now, bring down the next period i.e., 47.
Now, trial divisor is 1 x 2 = 2 and trial dividend is 47.
So, we take 22 as divisor and put 2 as quotient. The remainder is 3.
Next, we bring down the next period which is 13.Now, trial divisor is 12 x 2 = 24 and trial dividend is 313.
So, we take 241 as dividend and 1 as quotient. The remainder is 72.
Bring down the next period i.e., 69.
Now, the trial divisor is 121 x 2 = 242 and the trial dividend is 7269. So, we take 3as quotient and 2423 as divisor. The remainder is then zero.
Hence, square root of 1471369 = 1213
