Answer:

1st option

Step-by-step explanation:

$log( \frac{a {c}^{3} }{b} ) \\ = log(a {c}^{3}) - logb \\ = loga + log{c}^{3} - logb \\ = loga + 3logc - logb$

note that the cube is only for c not a

If ab= 7x-6 and bc= 12-2x. Then what does ac equal?

ra1l [238]

Ab = (7x-6) → b = (7x-6)/a (1)

bc = (12-2x) → b = (12-2x)/c (2)

Since (1) = (2) → (7x-6)/a = (12-2x)/c OR a/c = (7x-6)/(12-2x) (3)

Multiply both numerators of (3) by the SQUARE of their respective denominators;

(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:

ac = (7x-6)(12x-2x) or ac = -14x² + 96x - 72
