Write 0.000000065 in scientific notation.

Answer 1

To write \(0.000000065\) in scientific notation, you express it as a number between 1 and 10 multiplied by a power of 10.

1. Move the decimal point to the right until you have a number between 1 and 10. For \(0.000000065\), we move the decimal point 8 places to the right, giving us \(6.5\).
2. Since we moved the decimal point 8 places to the right, we express this as a negative exponent of 10.

Thus, \(0.000000065\) in scientific notation is:

\[ 6.5 \times 10^{-8} \]
