  3. If it ends in 6, ten’s digit is always odd (1, 3, 5, 7, and 9) otherwise it is always even.
  4. If a number is divisible by 4, its square leaves a remainder 0 when divided by 8.

What did you do determine whether the numbers are perfect squares?

You can also tell if a number is a perfect square by finding its square roots. Finding the square root is the inverse (opposite) of squaring a number. If you find the square root of a number and it’s a whole integer, that tells you that the number is a perfect square.

How do you find the square of a two digit number?

Steps for Squaring Two Digit Numbers
