Question

Find the least number by which 10368 should be (1) increased (2) decreased (3) mulupied
(4) divided to make it a perfect square.​

Answer 1

1,

here approx (101)^2 = 10368

so,

10368 > (101)^2,. but, 10368 < (102)^2

the required least number = (102)^2 - 10368

= 10404 - 10368 = 36

2, The no to be decrease = 10368 - (101)^2

= 10368 - 10201 = 167

3, multiplying the number with 2 make it a perfect square

that is = 10368 × 2 = 20736

√20736 = 144

4, devide the number with 2 make it a perfect square

10368 / 2 = 5184

√5184 = 72
