How do you write 0.000345 liters in scientific notation?

Answer 1

To convert a number to scientific notation:

1. Put the decimal point after the first non-zero digit;
2. Count how many digits the decimal point has to move to get back to its original position;
3. If the decimal point has to move left make this count negative;
4. Remove trailing zeros;
5. Put the number with the decimal point after the first non-zero digit and without the trailing zeros multiplied by 10 to the power of the count (made negative if necessary).

→ 0.000345 litres = 3.45 × 10^-4 litres
