Thread: Help simplifying basic expression with e

I have x/4 = lny This simplifies to y=e^(x-4)

Can someone help me understand the basic inverse properties of ln and e that would make x/(4 x ln)=y simplify to the answer above? Thanks.

Use the definition of the logarithm:

I'm not sure "simplify" is the right word.

You should have this property...The following Two statements are identical.

1)
2)

For suitable a, b, and c.

How does this apply to your problem statement?

Revise: See, SIRON even called it a "Definition". It's not really a "simplify" thing.

I understand the two statements and the conversion you guys give, but I don't know how to apply them correctly to this problem.

The natural log needs an argument and this has none. What is the question in full?

I don't remember the exact question. I understand it now. Thanks!
