Hey everyone :) Got stuckon a calc question and needed some help, my test is coming up :S Please & thankyouu!! Here's the question: Evauate the limit by change of variable: lim (x-->4) [(x^1/2)-2] / [(x^1/3)-8] The answer in the back of the book is 1/12. It MAY be wrong though. Here's my attempt: let u= x^1/3 u^3= x as x-->4 u^3--->4 u--->4^1/3 lim (u--->4^1/3) [(u^3/2)-2] / u-8 That's as far as I could get. Any help asap would be much much MUCH appreciated! cheers yall!
