Multiplication and division of values written in scientific notation. 

Multiplication and Division

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 105) ● (1.6 x 10-3) ● (3.07 x 106

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

[(7.33 x 108) ● (9.89 x 10-1)] / (6.12 x 1011)

Multiplication and Division Calculations

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 107) - (3.72 x 106)]

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:
