Sum of squares? Product?

By definition, ALL perfect squares are whole numbers!

81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.

No. Perfect squares as the squares of the integers, whereas irrational squares as the squares of irrational numbers, but some irrational numbers squared are whole numbers, eg √2 (an irrational number) squared is a whole number.

No - all squares of even numbers are even - while all squares of odd numbers are odd.

The numbers are 21 and 24. 576 - 441 = 135

The only squares I can think of related to life is "three squares", as in the expression, "All I need are 3 squares and a bed." That expression means, "All I need are three nutritious meals and a place to sleep."

Look for odd squares. Multiplying odd numbers results in an odd product.

With square roots if you have a number times itself or squared then that that product is that numbers square root example: 9x9= 81 81 square root is 9

4x2 - 36 = (2x-6)(2x+6) A very useful general rule is this : - When an algebraic expression is the difference of two squares e.g. a2 - b2 then it factorises into (a - b) (a + b).

That expression can't actually be factored without using complex numbers. If you want to use complex numbers, then it would come out as a "difference of squares":(x + i)(x - i)
