Question

Find the least number of 4 digits which is a perfect square . Find the square of this number.​

Answer 1

Answer:-

Perfect square is 1024.

Step-by-step explanation:

Greatest number of four digits = 1000.

Square root of 1000 = 32

Next higher number = 32.

So, the least number to be added to 1000 is 24.

1000 + 24 = 1024

Square of 32 = 1024.

Smallest 4-digit square number is 1024.

Hence, the smallest four digit number which is a perfect square is 1024.
