find the limit using limit laws. will rate 5 if work shown. lim x rightarrow - infinity(1+x6/x4+1) Solution Please rate fairly , Only the first rated answer gets karma points. (1 + x^6)/(x^4 + 1) = take x^4 common from both numerator and denominator = x^2[(1/x^6 + 1)/(1+1/x^4)] now if we apply limit as x-->- both 1/x^6 , 1/x^4 --->zero and as x-->- x^2 ----> answer = * (0+1)/(1+0) = I hope this is clear.
