5
square kilometers
Connecticut: 1, point, 4, 4, times, 10, to the power 41.44×10
4
square kilometers
What's the difference between the areas of the two states? Express your answer using either standard notation or scientific notation.

Answer 1

Arizona = 2.95×10^5 km^2
Connecticut = 1.44×10^4 km^2

Convert Connecticut to ×10^5: 1.44×10^4 = 0.144×10^5.

Difference = (2.95 − 0.144)×10^5 = 2.806×10^5 km^2 = 280,600 km^2.
