The sign for an exponent is ^. So it would look like 3^3 times 3^7.

anonymous · Answer

3^3 = 27
3^7 = 2187

anonymous · Answer

2187 times 27 = 59,049.

Knowing the properties of exponents would tell us that you add the exponents when you multiply numbers with the same base.

anonymous · Answer

So, you add the product of each, which would make 2214?
