Step-by-step Solution
To express the number \( 5,000,000,000 \) in scientific notation, you need to write it in the form \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
For \( 5,000,000,000 \):
1. Move the decimal point in \( 5,000,000,000 \) to the left until you have a number between 1 and 10. This gives you \( 5.0 \).
2. Count how many places you moved the decimal point. In this case, you moved it 9 places to the left.
3. Therefore, you can express the number as:
\[
5.0 \times 10^9
\]
So, \( 5,000,000,000 \) in scientific notation is \( 5.0 \times 10^9 \).
Quick Answer
\( 5,000,000,000 \) in scientific notation is \( 5.0 \times 10^9 \).
