(A) To find the least number to be added to $4042$ to make it a perfect square,we first find the square root of $4042$ by estimation.We know that $63^{2} = 3969$ and $64^{2} = 4096$.Since $4042$ lies between $63^{2}$ and $64^{2}$,the next perfect square is $64^{2} = 4096$.Therefore,the least number to be added is $4096 - 4042 = 54$.
