First of all thank you to all of you who will answer.
I am attending Calculus course at the university.
I found this limit particularly hard for me to compute:
Limit f x→inf = ?
And f(x) = (3^x+7^x)^(1/x)
I can only get to take it to an exponential form.
I send it to an online limit solver and the answer was: 7.
But I cannot past an indefinite inf^0
Thank you very much.
