Hi everyone!

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.
