Question: Get rid of ln(e) in result of Integral as it is 1

I am trying to evaluate the following INTEGRAL:

Int(2*e^(-(2/7)*j*Pi*n*t), t = 4 .. 5)

Maple gives me the following ANSWER:


Everything is correct but there is a ln(e) in the denominator of the answer. And we know that ln(e) = 1. 

Why does Maple not simplify this and get rid of the ln(e) from the answer?
