Multiplying monomials requires that you understand and can apply the laws of exponents. Let's quickly review the laws of exponents that will be needed.
Laws of ExponentsMultiplying Powers with the Same Base - Add the exponents. For example: (a3 ) (a2) = a5
Power of a Power - Multiply the exponents. For example: (a3)5 = a15
Power of a Product -find the power of each factor and multiply. For example: (3a)2 = 9a2-
