Question

write 0.000000065 in scientific notation. (1 point) 6.5 × 10^8 6.5 × 10^7 6.5 × 10^(-7) 6.5 × 10^(-8)

Explanation:

Step1: Recall scientific - notation form

Scientific notation is \(a\times10^{n}\), where \(1\leqslant|a|\lt10\) and \(n\) is an integer.

Step2: Move the decimal point

For the number \(0.000000065\), move the decimal point 8 places to the right to get a number between 1 and 10, which is \(a = 6.5\).

Step3: Determine the exponent \(n\)

Since we moved the decimal point 8 places to the right for a number less than 1, \(n=- 8\). So the scientific - notation is \(6.5\times10^{-8}\).

Answer:

D. \(6.5\times10^{-8}\)
