You can put this solution on YOUR website!
I'll pick up where you left off

+ln%28x%5E7%29=-6+

+x%5E7=e%5E%28-6%29+

+x=root%287%2Ce%5E%28-6%29%29+

Optionally, you can also write the answer as x+=+e%5E%28-6%2F7%29%5E%22%22

If you don't like negative exponents, then

+x=root%287%2C1%2F%28e%5E%286%29%29%29+

or

x+=+1%2F%28e%5E%286%2F7%29%5E%22%22%29
