lim(1+1/n)^(1/2) n趋向无穷用夹逼定理怎么求

lim(2^n+3^n)^1 (n趋向无穷) lim (1+1/2n)^n n趋向于无穷大 lim√1+1/n^2 n趋向于无穷大 高数 lim n趋向无穷 lim（3^(1/n)-1)ln(2+2^n) lim n趋向无穷大3n^3+n^2-3/4n^3+2n+1 lim(n/(n^2+1)+...+n/(n^2+n))x趋向于无穷 求解答过程~ 求极限 lim (1+2+3+...+n/n+2-n/2)趋向是正无穷lim (1+2+3+...+n/(n+2)-n/2)趋向是正无穷 lim(n趋向无穷){[(n^2+1)^(1/2)]/(n+1)}^n怎么解. 求极限:Lim(1+1/n-1/n^2)^n n趋向于正无穷 lim x趋向于无穷 (2^n+1+3^n+1)/(2^n+3^n)= 求lim趋向于无穷3^n+(-2)^n/3^(n+1)+(-2)^(n+1) 求解lim((3^1/n+4^1/n)/2)^n n趋向正无穷. 求极限 n趋向于无穷 lim（(根号下n^2+1)/(n+1)）^n 求极限lim(n趋向于无穷）(n+1)(根号下(n^2+1)-n) 紧急：求 lim n*sin(π(n^2+2)^0.5）*(-1)^n,n趋向无穷大； 求极限 lim(n+1/n+2)^n.n趋向无穷 n趋向于无穷大,lim n[ln(n+2)-ln(n+1)], lim(1+1/n+1）^n.趋向无穷大
