求n
更新1:
^是次方的意思 n不等於3
更新2:
我想知你地點計到等於3 答案唔係3
更新3:
to NDS: 你仲係錯 仲話數學勁.. to lkt0111022003: 你答岩左喇 有埋-1 既n係等於log5/log2 不過我都會選你

✔ 最佳答案
lhs=[(2+1)(2^2 +1)(2^4 +1)...(2^256 +1)+1]^(1/256)=(2-1)[(2+1)(2^2 +1)(2^4 +1)...(2^256 +1)+1]^(1/256) (a+b)(a-b)=a^2-b^2
= (2^2-1)[(2^2 +1)(2^4 +1)...(2^256 +1)+1]^(1/256)
=(2^4-1)(2^4 +1)...(2^256 +1)+1]^(1/256)
.........
=(2^512-1+1)^(1/256)
= 2^2
so,n=2

應該無後面ge -1

n = 3

[(2+1)(2^2 +1)(2^4 +1)...(2^256 +1)+1]^(1/256)=2^n -1
求n
a:3

[(2 1)(2^2 1)(2^4 1)...(2^256 1) 1]^(1/256)=2^n -1n=3我用心算嫁,選我最佳回答,我起中學拿過不少的獎,已後有數學難題你都可以黎問下我.
