Answer:

-57

Explanation:


log \frac{ {c}^(7) }{ {a}^(6) {b}^(2) } \\ \\ = log {c}^(7) - log( {a}^(6) {b}^(2) ) \\ \\ = log {c}^(7) - (log {a}^(6) + log{b}^(2) )\\ \\ = 7 \: log {c} - (6 \: log {a}+ 2 \: log{b})\\ \\ = 7 \:( - 9) - [6 \: ( - 5)+ 2 \: (12)] \\ \\ = - 63 - [ - 30 + 24] \\ \\ = - 63 - [- 6] \\ \\ = - 63 + 6 \\ \\ = - 57
