Mutliply each expression to match it with its simplified answer in scientific notation.
Remember to divide the factors and subtract the exponents. If the factor in your answer is more than one digit, move the decimal point to the left and decrease the exponent. For help, see the 10.7 notes video (youtu.be/VuYNYUBFS2s) and 10.7 classwork video (youtu.be/od7znSqxTbU).
