Question

Answer 1

`(a):\  x^{7}.(3y^{2}z^{3})^{3}:9(x^{2}y^{3}z^{3})^{2}`

`=27x^{7}y^{6}z^{9}:9x^{4}y^{6}z^{6}`

`=3x^{3}z^{3}`

`(c)\  24(x-2y)^{4}:12(2y-x)^{3}`

`=24(2y-x)^{4}:12(2y-x)^{3}`

`=2(2y-x)`

`=4y-2x`

Answer 2

a: \(=\dfrac{x^7\cdot27y^6z^9}{9x^4y^6z^6}=3x^3z^3\)

c: \(=\dfrac{24\left(2y-x\right)^4}{12\left(2y-x\right)^3}=2\left(2y-x\right)\)
