What are Square Numbers?
If a natural
number m can be expressed as n2, where n is
also a natural number, then m is a square number. For example: 4
can be expressed as 2 × 2 = 22, 9 can be expressed as 3 × 3 = 32.
The numbers 1, 4, 9, 16 … are square numbers. These numbers are also
called perfect squares.
Properties of Square Numbers:
If a number ends in 0, 1, 4, 5, 6 or 9, then it must be a square number
If a number has 1 or 9 in the units place, then it’s square ends in 1. For example: 92= 81, 112= 121, 192= 361, 212= 441
When a square number ends in 6, the number whose square it is will have either 4 or 6 in unit’s place. For example:
