Question

rewrite as an exponential equation
ln(x+y)=5

Answer 1

So, here you need to raise both sides by the exponential e. e^ln(x+y) = e^5. Can you see why we do this?

Answer 2

Not really?? I know when you deal with logs that e is the base of ln

Answer 3

I mean natural logs

Answer 5

That's right. So, you can think of ln(x) and e^x as being inverse to each other.

\[e^{\ln x} = x \]

Likewise, \[\ln e^{x} = x \]

These are inverse functions.

So, if we want to solve for x that's located in a natural logarithm, we need to apply its inverse function.
