Answer:
[tex]3.1\times 10^{10}[/tex]
Step-by-step explanation:
Scientific notation is a mathematical way to express a large in decimal form. In scientific notation the number is represented by a decimal number between 1 and 10 multiplied by ten.
For example : Scientific notation of 7500 is [tex]7.5\times 10^3[/tex]
The given number is 31 billion.
We need to write the given number in scientific notation.
We know that
1 billion = 1,000,000,000
Using this conversion, we get
31 billion =31,000,000,000
In can we written as
[tex]31,000,000,000=3.1\times 10,000,000,000[/tex]
[tex]31,000,000,000=3.1\times 10^{10}[/tex]
Therefore, the scientific notation of 31 billion is [tex]3.1\times 10^{10}[/tex].
