Assuming that the units of speed are also in minutes, for instance km/min or m/minute. Then you would not need to convert time into another unit. As for multiplying the bases of 10, remember that 10 = 10^1. So it would be 10^8+1 = 10^9. So the result would be 24 • 10^9 but in proper scientific notation it would be 2.4 • 10^10.
Yet, I believe you are working with the speed of light and thus you would need to convert 8 minutes into seconds which would be 8 • 60 = 480 seconds. Then do the following operation:
480 = 4.80 X 10^2
(4.80 X 10^2 seconds)(3.00 X 10^8 metres/second)
Simply multiply the whole numbers, and the bases of 10, and put in proper scientific notation.
Answer:
Step-by-step explanation:
Umm well mean you just have to use like terms. start by doing any math until there are no parenthesis, and then you basically just use like terms to solve it. (like if you have 
then you use like terms) I would need specifics to be able to evaluate more, but I hope this helps!
