Answer:
ln(x²y⁵/(5z⁷))
Step-by-step explanation:
You want to condense the logarithmic expression 2 ln(x) + 5 ln(y) - 7 ln(z) - In (5).
Rules of logarithms
The relevant rules of logarithms are ...
a·ln(b) = ln(b^a)
ln(ab) = ln(a) +ln(b)
ln(a/b) = ln(a) -ln(b)
Application
[tex]2\ln{(x)}+5\ln{(y)}-7\ln{(z)}-\ln{(5)}=\boxed{\ln\left(\dfrac{x^2y^5}{5z^7}\right)}[/tex]
