To express 6.32 billion in scientific notation, we first need to understand what a billion represents numerically.
A billion in the United States and many other parts of the world is equal to 1,000,000,000, which is [tex]\(10^9\)[/tex].
So, when we have 6.32 billion, we are essentially looking at:
[tex]\[
6.32 \times 1,000,000,000
\][/tex]
This can be written as:
[tex]\[
6.32 \times 10^9
\][/tex]
Thus, the scientific notation for 6.32 billion is:
[tex]\[
6.32 \times 10^9
\][/tex]
Therefore, the correct option is C.
