that when squared is equal to n.

number.
Square Roots and Perfect Squares
• Calculate all the perfect squares using the
whole numbers 0 through 50.
• For example: 0 X 0 = 0 would be the first
perfect square on your list
• Your next calculation would be 1 X 1 =
• Your last calculation will be 50 X 50 =
• Turn in by the end of the period
• PS No calculators, no agenda, work by hand
and individually.
