Question 679199

{{{e^(ln(x)) + ln (e^x) = 8}}}......the natural logarithm function, if considered as a real-valued function of a real variable, is the inverse function of the exponential function, leading to the identities:

   {{{e^(ln(x))=x}}}   if {{{x > 0}}}

and

    {{{ln(e^x) = x}}}


so, you have:


{{{x +x = 8}}}


{{{2x = 8}}}


{{{x = 4}}}
