Question

Help me with these equations

Answer 1

8.
`(8r^(2) )/(q^(2) )`

10.
`12x^(-1) y^(6) z`

Explanation:

8.
`(16p^(6)qr^(8) )/(2(p^(2)qr^(2))^(3) )` =
`(16p^(6)qr^(8) )/(2p^(6)q^(3)r^(6) )`=
`(8r^(2) )/(q^(2) )`

10.
`4x^(2) y` . 3
`(-2x^(4) y)^(0)` .
`x^(-3) y^(5) z` =
`4x^(2)y` .
`3(1)` .
`\\x^(-3) y^(5)z` =
`\\12x^(-1)yx^(6)z`
