1. Move the decimal point:
To get a number between 1 and 10, move the decimal point two places to the right: 0.079 becomes 7.9.
2. Count the decimal places:
You moved the decimal point two places to the right, so the exponent will be -2.
3. Write the result:
Therefore, 0.079 in scientific notation is 7.9 x 10⁻².
