Answer 2

1024 is the smallest four digit perfect square number

9801 is the largest four digit perfect square number

Explanation:

The smallest four digit number is 1000

∴ √1000 = 31.62 ...

∴ 31² = 961, a three digit number

∴ (31 + 1)² = 32² = 1024, a four digit number

Thus 1024 is the smallest four digit perfect square number.

The smallest five digit number is 10000

∴ √10000 = 100

∴ 100² = 10000, a five digit number

∴ (100 - 1)² = 99² = 9801, a four digit number

Thus 9801 is the largest four digit perfect square number.
