Question

Find the least number which must be subtracted from 6200 to
square. Also, find square root of the number so obtained​

Answer 1

to find the least number that must be subtracted from 6200 to obtain a perfect square, we will have to complete the square root of 6200 by long division . method.

$6200 \div 7 = 78 \times \ \frac{119}{7}$

so the remainder is 119 and 119 is the least number that must be subtracted from 6200to get a perfect square .

now, we will subtracted 119 from 6200

6200--119=6084

square root of 6084 by long division

$6084 \div 7 = 78\times \frac{0}{7}$

$\sqrt{6084} = 78$
