Problem:
in solving the problem, [(e^x^+e^-x^)/(2)]=3 ,
I arrived at u^2^-6u+1=0 (using "u" substitution of course), but cannot get any further. I am also just assuming the work I have done sofar is correct. Thank you!
*assume that numbers and quantities between ^...^ are a superscript and those between _...._ are subscripts*
