What is the number 7.3×10−8 written in decimal notation?
The number 7.3×10−8 written in decimal notation is 0.000000073.
To convert a number written in scientific notation to decimal notation, you can simply move the decimal point to the right or left according to the exponent.
In this case, we have 7.3×10^(-8). To convert it to decimal notation, we can move the decimal point 8 places to the left since the exponent is negative. If there are empty spaces, you can fill them with zeros.
Thus, 7.3×10^(-8) in decimal notation is 0.000000073.
To convert a number in scientific notation to decimal notation, you need to move the decimal point to the left or right based on the exponent. Here's how you can convert the number 7.3 × 10^(-8) to decimal notation:
1. Take the coefficient of the scientific notation, which is 7.3.
2. Move the decimal point to the left or right based on the exponent.
- Since the exponent is negative (-8), you need to move the decimal point to the left.
- For each negative exponent, move the decimal point one place to the left.
3. Start with the coefficient (7.3) and move the decimal point 8 places to the left: 0.000000073
Therefore, the number 7.3 × 10^-8 is written in decimal notation as 0.000000073.
