Answer:
3.42 ×
Step-by-step explanation:
To convert 3420000 to scientific notation, move the decimal to the left six places, so that the coefficient has one non-zero digit in front of the decimal, which is 3.42. The exponent on the base 10 will be positive six, , because the decimal was moved to the left six places. If the decimal was moved to the right, the exponent would have been negative.
Combine the coefficient and the base to get
3.42 ×
