To write a number in scientific notation, you need to move the decimal point to the right or left so that there is only one non-zero digit before the decimal point. The new number will then be multiplied by a power of 10.
In this case, the original number is 0.000000065. To move the decimal point to the right, we need to move it 8 places to the right to get a non-zero digit before the decimal point. This gives us 6.5.
Since we moved the decimal point 8 places to the right, we multiply the new number by 10 raised to the power of -8.
Therefore, the number 0.000000065 in scientific notation is 6.5 × 10-8.
So, the correct answer is 6.5 × 10-8.
