Question

-20t^5u^2v^3
———————-
48t^7u^4v

Answer 1

B.
`(-5v^2)/(12t^2u^2)\\`

Explanation:

Recall:

`(a^x)/(a^y) = a^(x -y)\\`

`a^(-x) = (1)/(a^x)\\`

Solution:

`(-20t^5u^2v^3)/(48t^7u^4v) \\ (-20)/(48) \cdot t^(5 -7) u^(2 -4) v^(3 -1) \\ -(5)/(12) \cdot t^(-2) u^(-2) v^2 \\ -(5v^2)/(12t^2u^2)`
