Ask the student a question, and give any hints about how they should answer this part.

As {choice2[0]}, {choice2[2]} approaches Unnamed gap

Note: infinity is simply entered by typing infinity

Advice

As {choice2[0]}, it appears {choice2[2]} approaches {choice2[1]}, but it isn't clear what this means. This is known as an indeterminate form of type {choice2[1]}. We can use a standard trick to write this expression to involve an indeterminate form of type {choice2[3]} in the exponent

{choice2[4]}

As usual, to deal with an indeterminate form of type {choice2[3]} we rewrite the product as a quotient, in this case, to involve an indeterminate form of type {choice2[5]} as such

{choice2[6]}

Now we apply L'Hospital's rule to the exponent, which means we now need to determine what {choice2[7]} approaches as {choice2[0]}. But this is again an indeterminate form so we repeatedly apply L'Hospital's rule until it is not an indeterminate form and we arrive at needing to determine what {choice2[4]} approaches as {choice2[0]}. Now that this is no longer an indeterminate form, it should be clear that the limit is {choice2[-1]}.
