    Finding Limits: Calculating vs. Uncertain Logic

    So lim(8/9)^x = lim e^(x*ln(8/9)) ln(8/9) (or ln (8 ) -ln(9)) is smaller than 0, resulting in a negative value for x*(ln(8/9)) So the result would be something of this form: lim e^(-x*...) or lim 1/e^(x*...) going towards 0 Am I correct? Now, the limit of (-9/8)^x can't be...

    Finding Limits: Calculating vs. Uncertain Logic

    Hi, I was doing some exercises on limits when I stumbled upon the following questions: (limits are always x->infinity) lim (2^x+1)/(3^x+1) 2nd one: lim (-9/8)^x The first one should be zero (3^x expands faster than 2^x), and the 2nd one doesn't seem to exist (according to maple and...
