Answer:
2.178 × 10^6
Step-by-step explanation:
Multiply 4840 × 450 to get 2,178,000
Move the decimal 6 places left then multiply by 10 to the 6th power, the number of places the decimal moved, to put it into scientific notation form. Scientific notation always has only one digit to the left of the decimal point.
