This concerns calculus practice/ limits of sequences and series/ convergence of sequences/ question 4:
Quoting the solution
My question is actually only about the last step, where both the nominator and denominator get divided by . The guy just pulls into the roots in the denominator. But should it not be, that:
The difference being that the root expressions converge to 0 instead of 1, and all other parts remaining the same,we have:
Can you confirm or am I missing something?
Thanks a lot in advance!
