Rhode Island is the smallest state. It has an area of approximately 1.55 x10 (to the 3rd power) square miles. Alaska is the largest state. The area of Alaska is 4.28 x 10 (to the 2nd power) times greater than the area of Rhode Island. What is the approximate area of Alaska in square miles?
(4.28 x 10 to the 2nd power) x (1.55 x 10 to the 3rd power)
I know how this process works. The equation I type above is correct, right?
in 2008 the total trade between the united states and japan was $2.04
Yes, the equation you have typed is correct. To find the approximate area of Alaska in square miles, you need to multiply the two given numbers: (4.28 x 10²) and (1.55 x 10³).
To multiply numbers in scientific notation, you multiply the coefficients (4.28 and 1.55) and add the exponents of the 10s (2 + 3).
(4.28 x 10²) x (1.55 x 10³) = (4.28 x 1.55) x (10² x 10³) = 6.634 x 10⁵
So, the approximate area of Alaska in square miles is 6.634 x 10⁵ square miles.
