Best ResponseYou've already chosen the best response.0not working so Lim x^4+x^32x/x^5+2x3 x>1

Best ResponseYou've already chosen the best response.1Do you mean l'Hôpital's Rule by limit law? In that case take the derivative of both the numerator and the denominator and then take the limit as x goes to 1.

Best ResponseYou've already chosen the best response.0I thought I need to factorize first

Best ResponseYou've already chosen the best response.1That can help sometimes, but factorising the denominator is difficult and l'H will crack it anyway...

Best ResponseYou've already chosen the best response.0No, using l'Hôpital's Rule allows you to take the limit as x goes to 1 of the top and bottom separately.

Best ResponseYou've already chosen the best response.1So, after differentiating separately yo now have this:\[\lim_{x \rightarrow 1}\frac{ 4x^3+3x^22 }{ 5x^4+2 }\]No 0/0 problem anymore, just set x=1 to see the result.
