Divide: `6x^3y^2z^2\ \ ` by`\ \ 3x^2y z` (2) `15 m^2n^(3\ )` by`\ 5m^2n^2` (3)`24 a^3b^3\ ` by`-8a b` (4) `-21\ a b c^2` by`\ 7a b c`

Explanation

(1) `6x^3y^2z^2` by `3x^2yz`
`=(6x^3y^2z^2)/(3x^2yz)`
`=2xyz`

(2) `15m^2n^2` by `5m^2n^2`
`(15m^2n^2)/(5m^2n^2)`
`=5`

(3) `24a^3b^3` by `-8ab`
`=(24a^3b^3)/(-8ab)`
`=-3a^2b^2`

(4) `-21abc^2` by `7abc`
`=(-21abc^2)/(7abc)`
`=-3c`
