1. Move the decimal point: Move the decimal point to the right until you have a number between 1 and 10. In this case, you need to move it seven places to the right:
0.0000007 -> 7.0
2. Count the moves: You moved the decimal point 7 places to the right. This means you multiplied the original number by 10 seven times.
3. Express the multiplier as a power of 10: Since you multiplied by 10 seven times, the exponent is -7.
Therefore, 0.0000007 in scientific notation is 7.0 x 10⁻⁷
