you need to do some of this on your own, but I will set you up for #7



and I'll give you some pointers:

• simply to a single fraction
• rationalize the numerator by multiplying the numerator and denominator by the conjugate of the numerator
• simplify the numerator
• cancel an h from the numerator and the denominator
• evaluate the limit (plug in 0 for h and simply)

lol i don't know how that happened

how did u go from step 2 to 3
and is the answer -1 or e^-1

Instead of blaming your professor maybe you should look at yourself

thank u my good sir, sorry that im retarded

probably not, else you would not be at your current stage of studying
but you might want to abstain from your organic greens when trying to solve problems
