Simplify the following. Please help asap....

48k^5/3k^7

12c^7d^4?15c^10d^3

(-xy)^4 x (-3x^-2)^3

20 Points!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

In order:

`(16)/(k^2)`

`180c^(17)d^7`

`-(27y^4)/(x^2)`

Explanation:

`48k^5/3k^7\\\\(48k^5)/(3k^7) \\\\(16)/(k^(7-5)) \\\\(16)/(k^2)`

`12c^7d^4*15c^(10)d^3\\\\12*15c^(7+10)d^(4+3)\\\\180c^(17)d^7`

`(-xy)^4 *(-3x^(-2))^3\\\\x^4y^4*(-3x^(-2))^3\\\\x^4y^4*-27x^(-6)\\\\-27x^(-6+4)y^4\\\\-27x^(-2)y^4\\\\-27*(1)/(x^2) *y^4\\\\-(27y^4)/(x^2)`

Hope this helps!
