Answer 1

using L'hopitales rule

Answer 2

differentiate the top and bottom
it the same limiting value

Answer 3

does it have to be (0/0) or (infinity/infinity) type to take the derivative

Answer 4

yes must be those if it remainsn that after differentiating diff again

Answer 5

but the original function is not (0/0) or (infinity/infinity) type

Answer 6

can be 1∞, 00, ∞0, 0 × ∞, and ∞ − ∞,

Answer 7

this one is (UND/UND)

Answer 8

no i think it is\[\infty \div-\infty\]

Answer 9

Thank you very much!!
