Answer:

2log(3)

Step-by-step explanation:

[tex]log(9x^5) + 5 log(\frac{1}{x})[/tex]

To simplify the given expression we apply log property

[tex]log m + log n = log (mn)[/tex]

[tex]n log m = log {m^n}[/tex]

[tex]log(9x^5) + 5 log(\frac{1}{x})[/tex]

[tex]log(9x^5) +log(\frac{1}{x})^5[/tex]

[tex]log(9x^5) +log(\frac{1}{x^5})[/tex]

now multiply the log terms

[tex]log(9x^5 \cdot \frac{1}{x^5})[/tex]

[tex]log(9)= log(3^2)= 2log(3)[/tex]
