0.073 in scientific notation
0.073 in scientific notation is written as 7.3 × 10^-2.
To write 0.073 in scientific notation, follow these steps:
1. Identify the non-zero digits in the number, which in this case are 7 and 3.
2. Count the number of decimal places between the non-zero digits and the original decimal point. In this case, there are two decimal places.
3. Rewrite the original number by moving the decimal point to the right so that there is only one non-zero digit to the left of the decimal point. The resulting number is 7.3.
4. Write the number from step 3 as a decimal number between 1 and 10 by including the decimal point and any necessary leading zeros. In this case, it is simply 7.3.
5. Write the power of 10 that indicates the number of decimal places you moved the decimal point in step 2, but make it negative. In this case, it is -2.
6. Combine the number from step 4 and the power of 10 from step 5, resulting in the scientific notation form of 0.073 as 7.3 x 10^-2.
Therefore, in scientific notation, 0.073 is written as 7.3 x 10^-2.
