Maybe this will help...

The original problem is actually based on this equality...

e^x = x^e

We know this is true at x = e, but is that the only point at which it is true? If it is the only point then for all x > e, e^x > x^e and pi > e thus e^pi > pi^e.

We can take the log() of both sides to get...

x = elog(x)

We know this works for x = e, let us now assume that it holds for another point, k*e where k != 1.

ke = elog(ke)
k = log(ke)
k = log(k) + 1

This was what I actually saw at point P.

We know this works for k = 1, but what about for some other value of k, like 1 + d?

1 + d = log(1 + d) + 1
d = log(1 + d)

Remember, at d = 0, they are equal. For d > 0, which increases faster? d or log(1 + d)? If two functions are equal and one function increases faster than the other, can they ever be equal again?

I attached a picture to help.
