A. [tex]\(6.32 \cdot 10^{15}\)[/tex]
B. [tex]\(6.32 \cdot 10^{12}\)[/tex]
C. [tex]\(6.32 \cdot 10^9\)[/tex]
D. [tex]\(6.32 \cdot 10^6\)[/tex]



Answer :

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.
