求lim[1-1/(n-3)]^2n.0→+无穷的极限麻烦写下过程,谢谢

求lim n→∞ (1+2/n)^n+3 求1.lim(3n-(3n^2+2n)/(n-1)) 2.lim(8+1/(n+1)) 3.lim根号n(根号(n+1)-根号(n-3)) 求极限lim 2/(3^n-1) 求极限lim [ 2^(n+1)+3^(n+1)]/2^n+3^n (n→∞) 求lim(n+1)(n+2)(n+3)/(n^4+n^2+1) lim n →∞ (1^n+3^n+2^n)^1/n,求数列极限 求极限lim(x→∞)（1/n+2/n+3/n..+n/n） 求极限,lim(x->0) (1-2sinx)^(3/x)lim(n->+∞) (n!-4^n) / (6+ln(n)+n^2) 数列求极限 lim (n->∞) (1/2+3/2^2+...+(2n-1)/2^n)lim (n->∞) n^k/a^nlim (n->∞) a^n/n!lim (n->∞) n次根号下(a) (a>0)lim (n->∞) (log_(a) n)/n lim(n+3)(4-n)/(n-1)(3-2n) lim(n^3+n)/(n^4-3n^2+1) lim[(n+3)/(n+1))]^(n-2) 【n无穷大】 lim(2^n+3^n)^1 (n趋向无穷) 求极限lim(n+1/n+3)^n如题 求极限n~∞,lim(n+1)/2n 求极限Lim（(n-x)/(n+2))^(n+1) lim (1+2/n)^n+4 n-->无穷大 求极限 求lim(n→∞)(3n^3+2n^2+1)/(2n^2+3)
