Question

Homework help please:
3lnx + 5lny -6lnz
I did:
ln x^3 +ln y^5 - ln z^6
What do I do next?

Answer 1

well you can use the log law of addition and subtraction

lna + lnb = ln(ab)
lna - lnb = ln(a/b)

but it doesn't really simplify the problem in any way

Answer 2

Did what I did sound or look right?

Answer 3

yes. you've used the log law of exponents which is fine

Answer 4

So they gave you that expression, did they say anything specific as to what they wanted you to do it? or just simplifying?

Answer 5

They just said to find a way to condense it

Answer 6

OK then use what I gave you

Answer 7

Thank you so much :)

Answer 8

final answer has one log term
