can you answer any question no matter how hard it is??

sure! but depending on the question, i'ld reply differently too.

incomprehensible--??? or what? or huh?
dumb--some sarcastic remark, or a tease.
normal--just reply what i feel.
intellectual--use dictionary to help :D
confusing--reply what i feel the question is about. ask again for clarification

haha, and it depends on my mood too... sometimes i'm having a headache and won't answer those confusing or intellectual ones. other times i'm just feeling pissed off, so i may not answer those incomprehensible or dumb ones :D

P.S. your question is interesting and comprehensible, that's why i have an answer for you! :)

yes

not this one

Find points at which f'(x)=0 when f(x)=(x+2/x^2+3)^2.?
f'(x) is f prime of x. A derivative of f(x).?

difficulty never puts me off answering a question
answering a stupid question is a whole different matter

For every question there is at least one answer.
Also know, that there is no problem that can not be solved.

can but not a good 1

Yes depending on the subject, and I like turnips.

Yes you can answer any question no matter how dificult it seems to you.....try me!

No.I dont answer question I dont understand or which I think are too hard for me since I have no experiance with them.Or I answer them but say I honestly dont know them.

Not a matter of CAN but WILL. Some deserve skipping! lol
