+42 how can i solve this?
3r^3 / 2r ?
will the anser is 3r^2 / 2 ?
it is on fraction form..
+9481 \(\large{\frac{3r^3}{2r} \\~\\ =\frac{3\,\cdot\, r\,\cdot\, r\,\cdot\, r}{2\,\cdot\, r}}\)
We can reduce the numerator and denominator by r ...(....and say r ≠ 0 ) .
\(\large{=\frac{3\,\cdot\, r\,\cdot\, r}{2} \\~\\ =\frac{3r^2}{2}}\)
Which is what you had !! 
Hey can you check this question out? My least favorite thing to do is these proofs. Just please try your best.
