x> 2

hartnn Group TitleBest ResponseYou've already chosen the best response.0
can u factor x^4 16 ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.0
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

hartnn Group TitleBest 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 ?

mm i dont remember! but once i have the numerator like that what can i do next?

hartnn Group TitleBest ResponseYou've already chosen the best response.0
\(\large a^2b^2=(a+b)(ab) \\ \text {so what is} (x^2)^24^2 \)

appleduardo Group TitleBest ResponseYou've already chosen the best response.0
so i'll get (x+2)^(2) * ( x2)^(2) ???
 one year ago

hartnn Group TitleBest 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?

appleduardo Group TitleBest ResponseYou've already chosen the best response.0
Wow! you're awesome !! :D mm what about this one? \[\frac{ \frac{ 1 }{ x } + \frac{ 1 }{ 2 }}{ x2 }\] x>2
 one year ago

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

appleduardo Group TitleBest ResponseYou've already chosen the best response.0
mm why?
