Question

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

Answer 1

To visualize better, look at it like this:

$\frac{3r^3}{2r}$

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 ($r^3$)

$r^3 - r^1 = r^2$

Put that on the top, and you get

$\frac{3r^2}{2}$
