wait, is that x^2 2 ?? if yes, there is no need to factor. just put x=2

mm maybe do this: x[x^(3) ] +16 ooh i was wrong, is x^(2)  4

hartnnBest ResponseYou've already chosen the best response.0
x^4 16 now 16 is 4^2 , isn't it ? so you can write numerator as \(\large (x^2)^24^2\) use a^2b^2 = .... formula, do u know ?

\(\large a^2b^2=(a+b)(ab) \\ \text {so what is} (x^2)^24^2 \)

appleduardoBest ResponseYou've already chosen the best response.0
so i'll get (x+2)^(2) * ( x2)^(2) ???

hartnnBest ResponseYou've already chosen the best response.0
?? no. \(\huge (x^2)^24^2=(x^2+4)(x^24)\)

ooh!! i understand now ! :D so then i can cancel x^(2)  4 and the limit will be 8 right?

Wow! you're awesome !! :D mm what about this one? \[\frac{ \frac{ 1 }{ x } + \frac{ 1 }{ 2 }}{ x2 }\] x>2
 one year ago

hartnnBest ResponseYou've already chosen the best response.0
that limit does not exist!
