Good work.
Another way to look at this is how the decimal point moves with respect to the power of ten.
*If the power is positive, the decimal point moves to the right the same number of places as the power of ten that you are calculating.
Ex: 2.7183 * 10^3
For this example, the decimal point will move three places to the right because 2.7183 is being multiplied by ten to the 3rd power.
2.7183 * 10^3 = 2718.3
*If the power is negative, the decimal point moves to the left the same number of places as the power of ten that you are calculating.
Ex: 3.1416 * 10^2
For this example the decimal point will move two places to the left because 3.1415 is being multiplied by ten to the 2nd power.
3.1416 * 10^2 = 0.031416
