Problem of the Week - Sino Canada School
... The problem itself is not very difficult once you determine what it is asking. So before looking at the solution, let us examine some perfect squares. The numbers 4 and 9 are both perfect squares that have only one prime number as a factor, 4 = 22 and 9 = 32 . The number 36 is a perfect square since ...
