f'(x) = x (1/(1+e^{x^2}) )( e^{x^2}) (2x) + ln( 1+ e^{x^2} )
= 2x^2 e^{x^2} / (1+e^{x^2}) + ln( 1+ e^{x^2} )
f'(5) = 2(25) e^25 /(1+e^25) +ln(1+e^25) .
(all the previous answers are not exactly correct!!!!!)

f(5) = 5 ln (1 + e^5^2)
f(5) = ln5 x ln 2(e^5)

f(x) = xln(1 + e^(2x))
f'(x) = ln(1 + e^(2x)) + (((2xe^(2x))/(1 + e^(2x)))
f'(5) = ln(1 + e^(2(5))) + ((2(5)e^(2(5)))/(1 + e^(2(5)))
f'(5) = ln(1 + e^10) + ((10e^10)/(1 + e^10))
f'(5) = about 9.99959
