Explanation
We are given the following:
![\begin{gathered} \log_bA=3 \\ \operatorname{\log}_bC=2 \\ \operatorname{\log}_bD=5 \end{gathered}]()
We are required to determine the value of:
![\operatorname{\log}_b((A^5C^2)/(D^6))]()
3We know that the multiplication and division laws of logarithm state:
Therefore, we have:

We also know that the power law of logarithm states:
Therefore, we have:

Hence, the answer is -11.
