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.

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

In can we written as

$31,000,000,000=3.1\times 10,000,000,000$

$31,000,000,000=3.1\times 10^{10}$

Therefore, the scientific notation of 31 billion is $3.1\times 10^{10}$.
