Hi To solve this problem lets first expand through solve for dervitive set y prime =0 solve for x put x into y equations and proove one of smaller thne the other

Sorry, what is 'lim'? Limit?
yes
Thanks so far, although I still don't understand this part: now you said a,b,c,x >0 so if we take a lim x-> 0 limx->0 ab/cx + b/c +a/c + x/c
oh nvm im very wroung hehe sorry take the derivtive solve for x at y prime=0 you should get 2 values find the lower value by pulling both into original y equations lower one is ur result in this cause ull have to prove on os smaller then the other
Sorry, I don't really understand? :S
