Also, Since, Thus, by the squeeze theorem.
Hello, Nichelle14! I tried to divide the numerator and denominator by . . .Was not successful. What should I do next? Divide top and bottom by The numerator is: . The denominator is: . Recall that: if , then Therefore, the limit is: .

I think the trick here is that you will divide all the terms by the largest term in the expression(it is useful when the limit tends to infinity) Keep Smiling Malay
