  Q: How is the number 720,000,000 written in Scientific Notation?

  A: 7.2 x 108

   

  Why is 720,000,000 written as 7.2 x 108 in scientific notation?

  The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

  Calculating scientific notation for a positive integer is simple, as it always follows this notation:

  a x 10b

  Follow the steps below to see how 720,000,000 is written in scientific notation.

  Step 1

  To find a, take the number and move a decimal place to the right one position.

  Original Number: 720,000,000

  New Number: 7.20000000

  Step 2

  Now, to find b, count how many places to the right of the decimal.

  New Number:7.20000000

  Decimal Count:  12345678

  There are 8 places to the right of the decimal place.

  Step 3

  Building upon what we know above, we can now reconstruct the number into scientific notation.

  Remember, the notation is: a x 10b

  a = 7.2 (Please notice any zeroes on the end have been removed)

  b = 8

  Now the whole thing:

  7.2 x 108

  Step 4

  Check your work:

  108 = 100,000,000 x 7.2 = 720,000,000
