|
Answer» The smallest 6 digit number is 100000 We find the square root of 100000 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.
