Question

how do you expand ln (x^5/2y) ?

Answer 1

x.x.x.x.x/2y you mean expanded form?

Answer 2

yes

Answer 3

You can use the rule of logarithms -- specifically, that division turns into subtraction:

\[\ln{\frac{x^5}{2y}} = \ln x^5 - \ln 2y\]

Answer 4

and that's it?

Answer 5

I believe, but it depends on what `expand' means :) That's fairly typical, though.

Answer 6

thanx a lot you rule!

Answer 7

Glad to help! :)

Answer 8

one more step.
\[5ln(x)-ln(2y)\]
\[2ln(x)-ln(y)-ln(2)\]

Answer 9

typo in the last one. should be \[ln(\frac{x^5}{2y})=5ln(x)-ln(y)-ln(2)\]

Answer 10

Damn, good call. satellite.
