Find the square root by division method 529
Answers
solution
The use of the number of digits in square root of a number is useful in the following method
consider the following steps to find the square root of 529
Step 1
Place a bar over every pair of digits starting from the digit at ones place if the number of digits in its ok then the leftmost single- digit toowill be there about that we have 529
Step 2
Find the largest number whose square is less than or equal to the number under the extreme left bar (2²<5<3²).Take this number as the divisor and quotient with the number under the extreme left bar as the division (here 5).Divide and get the reminder (1 in this case)
Step 3
Bring the number under the next bar example 29 this case to the right of the reminder ,so the new divisor is 129
Step 4
Double the quotient and enter it with the blank on its right
Step 5
Guess a largest possible digit to fill in the blank which will also become the new digit in the quotient such that when the new divisor is multiplied to the new question the product is less than or equal to the dividend ,In this case 42×2=84
As 43×3=129,so we choose the new digits as 3.we get the reminder.
Step 6
Since, the reminder is 0 and no digits are left in the given number therefore
