Unit 1b-4: Multiplying and Dividing Scientific Notation

Multiply each expression to match it with its simplified answer in scientific notation.
Remember to multiply the factors and  add the exponents.  If the factor in your answer is more than one digit, move the decimal point to the left and increase the exponent.
