Answer:
C. 4218.75
Step-by-step explanation:
1. We can see that A, C, and D are given to us. (A=3, C=2, and D=5)
2. You input the values of A, C, and D into the equation.
--> [tex]log_b\frac{(3)^3 (5)^4}{(2)^2}[/tex]
3. Simplify.
--> [tex]log_b\frac{(27)(625)}{4}[/tex]
= [tex]log_b\frac{16,875}{4}[/tex]
= [tex]log_b 4,218.75[/tex]
