okay, lets say that you and a friend (two of you) have have an apple tree and each of you pick two apples from the tree, if you count all the apples you have picked you will see that you have four apples in total (two groups of two, 2 x 2 = 4).
The next day you and two friends (so now there's three of you) go to the apple tree and pick three apples each. Now if you count all the apples you will see that you have nine apples in total (three groups of three, or 3 x 3 = 9)

How could you find the number with the prime factorization of 2x2 x 3x3?
To find the original number when given the prime factors, we have to work backwards. First, we simplify into 2 squared times 3 squared. (2x2) x (3x3) Then we expand the brackets. 4 x 9 = 54 Therefore 54 is the number, with 2x2 and 3x3 as the prime factors.
