###### Logarithms and Exponetials Questions

3 months ago

The question is:

ln(2x+1) = ln (x) +2

I've done:

ln(2x+1) = ln^2 +2

2x+1 =e^2 x

but I'm not sure what to do next.

ln(2x+1) = ln (x) +2

I've done:

ln(2x+1) = ln^2 +2

2x+1 =e^2 x

but I'm not sure what to do next.

$2x+1=e^2 x$ is right, now just rearrange for $x$.

Don't be put off by the $e^2$, it's just a number about 7.389 so it should be a short rearrangement.
