Question 119481: Good evening ma'am or sir, please help on how to solve this problem involving expressions with exponents. I didn't know what I will do with this one.
4). Alpha Centauri is 4.3 light years from Earth. Express this distance in kilometers in scientific notation. (A light year is 9.5*10^12 km).
Thank you very much!!!
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
The units need to come out right. First, just write an equation with
units only, like this:
km = (light-years)(km/light-year)
Notice, on the right side, light-years on top cancels the light-years
on the bottom, and you're left with km = km as you should.
Let d = distance in km.
