化简2^2N+1-(4^2N+16^N)求大神帮助

化简2^2N+1-(4^2N+16^N)求大神帮助
2^2N+1-(4^2N+16^N) =2^2N+1-（2^2）^2N+(2^4)^N =2^2N+1-2^4N+2^4N =2^2N+1

2^2N+1-(4^2N+16^N) =2^2N+1-2^4N-2^4N =4^N-2X2^4N =4^N-4^4N =4^N(1-4^3N)

化简：1/(n+1)(n+2)+1/(n+2)(n+3)+1/(n+3)(n+4) 化简：2^4n+1-(4^2n+16^n) 化简:2^4n+1-(4^2n+16^n) [3n(n+1)+n(n+1)(2n+1)]/6+n(n+2)化简 [3n(n+1)+n(n+1)(2n+1)]/6+n(n+2)化简化简n分之n-1+n分之n-2+n分之n-3+.+n分之1 化简n分之n-1+n分之n-2+n分之n-3+.+n分之1 2^n/n*(n+1) 证明不等式：(1/n)^n+(2/n)^n+(3/n)^n+.+(n/n)^n 化简(n+1)(n+2)(n+3) 根号【（2n+1）/（n²+n）】平方-4/（n平方+n ）化简化简[n^2+(n+1)^2]/n(n+1) 化简额 lim(n+3)(4-n)/(n-1)(3-2n) lim(n^3+n)/(n^4-3n^2+1) 化简16^n+2×4^n-1/8^2n×5^2n+4×2^n/5^2n+3×2^n+3 Sn=n(n+2)(n+4)的分项等于1/6[n(n+2)(n+4)(n+5)-(n-1)n(n+2)(n+4)]吗? (n+2)!/(n+1)! (n+1)(n+2)/1 +(n+2)(n+3)/1 +(n+3)(n+4)/1
