Give an appropriate answer.

Let lim x→6 f(x)=81. Find lim x→6 4^√f(x).

6 answers

that would be 4^√81 = 4^9

Was there some reason you didn't just plug in 81 for f(x)?
4^9 = 262144 Is this the answer!!

I got 3.
So, how did you get 3? Maybe I can show where you went wrong.
Ah. I see where I misread your question. You apparently meant "4^√" to mean 4th root (∜).

In that case, the answer is indeed 3.
My fault. Sorry about that. Thank you
Also suppose If lim x→6 had been lim x→5 would that had been changed the answer. Or it would be same.
