​

Answer 1

Answer:

.Find the least number to be added to get 

a perfect square 123456 

Soln First we find 123456 by division method

9<12<16

32<12<42

62×2=124

63×3=189

65×5=325

66×6=396

702×2=1404

hence (51)62<123456<(352)2

we calculate (352)2−123456

=123904−123456

=448

hence least number to be added to get a 

perfect square is 448.

since 123456+448=123904=(352)2
