Questions: Convert 2,500,000,000 to scientific notation.

Solution Steps

To convert a number to scientific notation, we need to express it as a product of a number between 1 and 10 and a power of 10. We do this by moving the decimal point in the number to the left until only one non-zero digit remains to the left of the decimal. The number of places we move the decimal point becomes the exponent of 10.

We start with the number $2,500,000,000$.

To convert this number to scientific notation, we move the decimal point to the left until only one non-zero digit remains to the left of the decimal point. For $2,500,000,000$, we move the decimal point 9 places to the left, resulting in $2.5$.

The number of places we moved the decimal point becomes the exponent of 10. Since we moved the decimal 9 places, the exponent is 9.

Combine the number $2.5$ with the power of 10 to express the original number in scientific notation: $2.5 \times 10^9$.
