Suppose n>=9 is an integer. Let u= n^1/2 + n^1/3 + n ^1/4.
Then which of the following relationships between n and u is correct?
A. n=u
B. n>u
C. n<u
D. none of the above.
Also, I have a doubt in dse 2008 question 55.
http://economicsentrance.weebly.com/uploads/1/1/0/5/1105777/28_june_2008_option_a.pdfI'm getting the limit to be 0 for all x other than 0, and infinity for x=0. Plz confirm this. And if this is correct then is the answer d? I mean if a sequence has an infinite limit do we say the limit does not exist?
