Integral of (e^x)/(e^x +8): I get log(8 + e^x) + C

[CalcEqualsUgh]

Evaluate the integral of:

(e^x)/(e^x + 8)

I get an incorrect answer of log (8 + e^x) + C

Should you perhaps be including the absolute-value bars for the log...?

Your answer is correct. Absolute value bars are not necessary as e^x is always >0.
