Write 0.000000065 in scientific notation.
0.000000065 in scientific notation is 6.5 x 10^-8.
The speed of light is about 671,000,000 miles per hour. How will you write this number in scientific notation?
To write 0.000000065 in scientific notation, move the decimal point 7 places to the right to get 6.5. Now, we can express this number as 6.5 x 10^(-8) in scientific notation, where the exponent -8 represents the number of decimal places the decimal point was moved.
To write a number in scientific notation, follow these steps:
1. Start by identifying the non-zero digits in the number. In this case, the non-zero digits are 6 and 5.
2. Write these digits as a decimal number between 1 and 10. In our example, it will be 6.5.
3. Count the number of decimal places you moved the decimal point to get to this number from the original number. In this case, we moved the decimal point 8 places to the right (from 0.000000065 to 6.5).
4. Express this count as a power of 10. Since we moved the decimal point 8 places to the right, the power of 10 will be -8.
5. Write the number in scientific notation by combining the decimal number from step 2 and the power of 10 from step 4. In our example, it will be 6.5 x 10^(-8).
Therefore, 0.000000065 in scientific notation is 6.5 x 10^(-8).
