Question

find the least number of six digits which is a perfect square

Answer 1

The smallest 6 digit number is100000 We find the square root of100000 with a calculator: =316.227766 We take the next larger whole number 317 We square 317 317² = 100489 That's the smallest perfect square which is a 6-digit number, because when we square 316 we only get 99856, which is only a 5-digit number.
