**Solved! d/dx |x+2|^x**

## Homework Statement

I need someone to explain this:

## Homework Equations

I guess the following are of relevance...

[tex]\frac{d}{dx} |x| = \frac{x}{|x|}[/tex]

[tex]\frac{d}{dx} a^x = a^x ln a[/tex]

## The Attempt at a Solution

The solution is up there. I just need help understanding why this is the solution.

Normally, iirc a derivative of an expression is the outer derivative times the inner derivative, but here it seems to be the original expression times the inner plus the outer derivative, or something in between... eh.
