Question

square root of 72 by division method​

Answer 1

8.485

Step-by-step explanation:

Start by grouping the digits into pairs, beginning with the units digit. The pair formed and remaining digit (if any) is called a period. After establishing the largest square number equal to or slightly less than the first period, use it as both the divisor and the quotient. Multiply the divisor and quotient then subtract it from the first period. Then, write the next period to the right of the remainder. As a result, a new dividend is formed. This becomes the new dividend.

Now, the new divisor is found by using two times the quotient and adding with it an ideal digit that acts as the next digit of the quotient. The number is chosen, such as the product of the digit, and the new divisor's value equal to or slightly less than the new dividend. Finally, repeat the second, third, and fourth steps until all the periods have been incorporated or taken up. The quotient obtained is the required square root of the given number.
