Hello from home amidst boxes and crates. Sorry I couldn’t be there today. Seems like a lot of people had trouble (or didn’t try) the work from today. I added a couple of examples to the bottom of the page but the problems are really just like the work from yesterday except you need to keep track of your exponents and if you get and answer like 25 x 1014 then you have to change it to (2.5 x 101) x 1014 which is 2.5 x 1015. Good luck. I’ll have more (hopefully easier) work on Monday. MAKE SURE you did yesterday’s work – no excuses on that one.
