a perfect square is any integer times it self for example:

3 x 3= 9, so 9 is a perfect square

If you do not have a calculator with 'square root' function or an xy key then you will have to do it by the process of guessing and elimination.

To find if a number (N) is a perfect square:

  • Divide the (N) by a number (D) that is reasonabe.
  • If the result is larger than (N) then try a larger (D).
  • If the result of N/D is smaller than (D), choose a smaller (D).
  • Continue until you have narrowed (D) down to an integer that is the square root of (N) or come to the conclusion that (N) is not a perfect square - (D-1)2 is smaller than (N) and D2) is larger

To find if a number (N) is a perfect cube:

  • Do as above but divide the result of N/D by D again - Do N/D2 and compare that result to D

What is a perfect square and perfect cubed number?

To find a number that is both a perfect square and a perfect cube, we must solve x2 = x3 over x ∈Z+. The only two solutions to this equation are 0 and 1, or x = {0,1}. Therefore, zero and one are the only two numbers that are both perfect squares and perfect cubes. --In easier terms: a perfect square is a number that can be "square rooted" and have no remainder. Like, 144. The square root is 12 therefore 144 is a perfect square. A perfect Cube is the same except that it must be "cubed rooted". Like 27. The cube root of this number is 3 therefore 27 is a perfect cube.

How do you find a perfect cube?
