$169256441$ $169" "256" "441$ are perfect squares

A square number is formed by multiplying a number by itself.

$x \times x = x^{2}$ $x xx x = x^2$

Perfect squares are formed when a whole number is multiplied by itself. They will always be positive.

The first ten perfect squares are:

$149162536496481100$ $1" "4" "9" "16" "25" "36" "49" "64" "81" "100$

Other perfect squares could be:

$13^{2} = 169 or 16^{2} = 256 or 21^{2} = 441$ $13^2 = 169" "or 16^2 =256" "or 21^2 = 441$

A perfect square is a number whose square root is a whole number.
