To square something is to multiply it by itself. 3 squared would be represented like this: 3². The two indicates the number of 3's you're multiplying together: 3*3.
So 3² = 3*3 = 9
Cubed is a 3 instead of a 2, represented like this: 3³, which means 3 3's multiplied together.
3³ = 3*3*3 = 27
Hope this helps.
