Question

Express as a single natural log: 4lnx+3lny-5lnz

Answer 1

You probably know these rules:

ln(a)+ln(b)=ln(ab)

ln(a)-ln(b)=ln(a/b)

k*ln(a)=ln(a^k)

Use all three rules here (last one first).

Answer 2

\[\ln \frac{ x^{4}y^{3} }{ z^{5} }\]

Answer 3

how does that look?

Answer 4

Great!

Answer 5

Just follow the rulez...

Answer 6

nice! thanks for the assistance on that one! :D

Answer 7

YW!
