Thread: Direct Comparison Test Question

LIMIT COMPARISON TEST (sorry)

1/[2(square of n) + (cube root of n)] compared with 1/(square of n)


I understand how to do the problem, my question is: how do I know to choose that equation to compare it with when there are two different n's in the denominator (n^1/2) and (n^3/2).

What exactly is the problem?

compared with

Or did you mean to say "square root of n", in which case it's

compared with

I meant square root of n, thanks for catching that!
