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.
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
Now, to find b, count how many places to the right of the decimal.
Decimal Count: 12345678
There are 8 places to the right of the decimal place.
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
Check your work:
108 = 100,000,000 x 7.2 = 720,000,000
