Write 0.00000065 in scientific notation

6.5 x 10^-7

To write the number 0.00000065 in scientific notation:

1. Start by moving the decimal point to the right of the first nonzero digit. In this case, the first nonzero digit is 6.
--> 6.5

2. Count the number of places you moved the decimal point. In this case, we moved it 7 places to the right.
--> 6.5 x 10^(-7)

Therefore, 0.00000065 in scientific notation is 6.5 x 10^(-7).

To write 0.00000065 in scientific notation, we need to shift the decimal point to the right so that there is only one non-zero digit to the left of the decimal point. In this case, we need to shift the decimal point six places to the right.

0.00000065 = 6.5 × 10^-7

The number 6.5 is the decimal number we get after shifting the decimal point, and 10^-7 represents "10 raised to the power of -7," which means moving the decimal point seven places to the left.
