Simplify the following using scientific notation:

(8.76 x 109)(6.52 x 10-3)/13.27 x 105

  • 4.3 x 101
  • 0.43 x 101
  • 43 x 10-1
  • 43.06 x 10-2

Using scientific notation, this problem would have two main steps.

First, you would multiply the numbers in the numerator (8.76 x 6.52) and divide them by the number in the denominator (13.27). Answer is approximately 4.3.

Secondly, you would divide the exponents of the numerator and denominator (9 (-3))-5. Answer is 1 (or 101). Now multiply the two together and you get 4.3 x 101.

By definition, scientific notation is a number greater than or equal to 1 and less than 10 times 10 raised to some power. Option 1 is the only one that meets that criteria.
