Answer 7

you don't want 0 at all

Answer 8

Differentiate Numerator and Denominator Seperately then apply the limit

Answer 9

L'hopital is taking the derivative of the numerator and denominator

Answer 10

you can factor. DO NOT USE L'HOPITAL if it is not in an 'indeterminate' form or you will gain a useless answer - it won't make sense
