Practice: Perform the following calculation for the image below to the right number of sig figs:

[(11.422-0.800) + (8.0 + 1.115)/0.0720] 1.33 x 10^{-5}

**Multiplication** and **division** of values written in scientific notation.

When multiplying or dividing your final answer will have the least number of significant figures.

Concept #1: Multiplication and Division Operations

Example #1: Using the method discussed above, determine the answer when the following values are multiplied.

(2.134 x 10^{5}) ● (1.6 x 10^{-3}) ● (3.07 x 10^{6})

Example #2: Using the methods discussed above, determine the answer for the following mixed operations question.

[(7.33 x 10^{8}) ● (9.89 x 10^{-1})] / (6.12 x 10^{11})

Example #3: Perform the following calculation to the right number of sig figs:

[(9.12 x 10^{-5}) + (6.33 x 10^{-3})] / [(1.15 x 10^{7}) - (3.72 x 10^{6})]

Practice: Perform the following calculation for the image below to the right number of sig figs:

[(11.422-0.800) + (8.0 + 1.115)/0.0720] 1.33 x 10^{-5}

Practice: Compute the following and determine the correct number of significant figures in the answer for the image below:
