This quiz will continue our review of exponents and how they work. Besides being able to add and subtract numbers with exponents, we can also multiply and divide. The rules regarding addition and subtraction of numbers with exponents continue to apply here so letâ€™s look at the following practice example and see how the problem is worked to find the solution.

3^{2} x 2^{4} =

3 x 3 = 9

2 x 2 = 4 x 2 = 8 x 2 = 16

9 x 16 = 144

__Solution__: 3^{2} x 2^{4} = __144__
