To convert a number to scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. The number of decimal places we moved is the exponent of 10. In this case, we need to move the decimal point 3 places to the right to get 4.56, which gives us an exponent of -3. Therefore, the scientific notation of −0.000456 is −4.56E−04.
