Question

HELPPPPPPPPPPPPPP PART 4

Answer 1

13) 1

14) st^3

15) m^-2n^-2

Explanation:

`13) \: (xy)/(xy) = 1`

`14) \: \frac{ {s}^(2) {t}^(4) }{st} = s {t}^(3)`

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

The above solutions are basic mathematical division operation.
