Answer 1

Explanation:

If you need help with how I got my answer, you can ask me.

`\frac{2yx {}^( - 4) }{(x {}^( - 4)y {}^(4)) {}^(3) * 2x {}^( - 1)y {}^( - 3) }`

`\frac{2yx {}^( - 4) }{x {}^( - 12)y {}^(12) * 2x {}^( - 1)y {}^( - 3) }`

`\frac{2y x {}^( - 4) }{2x {}^( - 13) y {}^( - 9) }`

`= x {}^(9) y {}^( - 8)`

`= \frac{x {}^(9) }{y {}^(8) }`

12.

`( \frac{2u {}^( 4) }{ - u {}^(2)v {}^( - 1) * 2uv {}^( - 4) } ) {}^( - 1)`

`( \frac{2u {}^(4) * 1 }{ - 2 {u}^(3)v {}^( - 5) } ) {}^( - 1)`

`( - u v {}^( 5) ) {}^( - 1)`

`= - u {}^( - 1) v {}^( - 5) = - \frac{ 1}{uv {}^(5) }`

13.

`- \frac{2m {}^(4)n {}^( - 1) }{( - m {}^(2)n {}^( - 2)) {}^( - 1) * - nm {}^( - 3) }`

`- \frac{2m {}^(4)n {}^( - 1) }{ - m {}^( - 2) n {}^(2) * - nm {}^( - 3) }`

`- \frac{2m {}^(4) n {}^( - 1) }{m {}^( - 5)n {}^(3) } = - 2m {}^(9) n {}^( - 4)`

`= - \frac{2m {}^(9) }{n {}^(4) }`

14.

`( \frac{x {}^(3)y {}^( - 4) }{ - {x}^(2) y {}^( - 3) * yx {}^(0) } ) {}^(3)`

`( \frac{x {}^(3)y {}^( - 4) }{ - {x}^( - 2)y {}^( - 2) } ) {}^(3)`

`( - {x}^(5) y {}^( - 2) ) {}^(3) = - x {}^(15) y {}^( - 6)`

`- \frac{x {}^(15) }{ {y}^(6) }`

15.

`- \frac{yx {}^(4) * - {y}^(3) z { }^( - 4) }{(z {y}^(2) ) {}^(4) }`

`- \frac{ - y {}^(4) x {}^(4) z {}^( - 4) }{ {z}^(4) y {}^(8) } = - y {}^(4) x {}^(4) z {}^( - 8) = - \frac{(xy) {}^(4) }{ {z}^(8) }`

16.

`\frac{h {}^(7)j {k}^(4) }{4h {}^(4) } = (1)/(4) h {}^(3) = \frac{h {}^(3) jk {}^(4) }{4}`
