I've been on vacation this week and my math teacher just gave me a packet of makeup work to do. a lot of them are questions like this. how do i do these? 3r^3/2r

To visualize better, look at it like this:

First, see if you can simplify 3/2. You can't, so leave it like that.

The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top ()

Put that on the top, and you get

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
