Question

What is the greatest perfect square of 1290

Answer 1

It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!

Answer 2

There can't be greatest perfect Square of an Integer or Natural Number.There is only one Square of a Natural Number.

So, (1290)²

=1290×1290

=(1300-10)×(1300-10)

=1300×(1300-10)-10×(1300-10)

=1,690,000-13,000-13,000+100

=1,690,000-26,000+100

=1,664,000+100

=1,664,100
