Answer:8. 4.2*10^–3 and 7. No

Step-by-step explanation: To find the answer for question #8, move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.
