Answer:


\log_7(u^5v^8)

Step-by-step explanation:

To write the expression as a single logarithm, we will use the following properties


\begin{gathered} 5\log_7x=\log_7x^5 \\ \log_7x+\log_7y=\log_7(xy) \end{gathered}

Using the first property, we get


5\log_7u+8\log_7v=\log_7u^5+\log_7v^8

Then, we need to use the second property, so


5\log_7u+8\log_7v=\log_7(u^5v^8)

Therefore, the answer is


\log_7(u^5v^8)
