3. Evaluate the following limits without using L'Hopital's rule, if exists. If not, determine whether the one-sided limits exist (finite or infinite). (a) lim 1-32x5 (b) lim 2a 1 1-8x3 *-a. (c) lim 1+x X-0 *1-x/ 4. Evaluate the following limits without using L'Hopital's rule, if exists. (a) lim (b) lim In (1+8) X-+0 394x-x2 x-+co In(1+2) (c) lim In(1+8*) X- -co In(1+2*) (d) lim xx x4+ 00 20*+2-2 (e) lim x-+ 0 86*-x-2
