(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
=2^512-1
(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
=2^512-1
原式=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)=(2^2-1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)=(2^4-1)(2^4+1)(2^8+1)…(2^256+1)=2^512-1
化简(2+1)(2^2+1)(2^4+1)(2^8+1)…(2^256+1)
化简(2平方+1)(2四次方+1)(2八次方+1).......(2三十二次方+1)
(2+1)(2^2+1)(2^4+1)(2^6+1)(2^8+1)(2^10+1)......(2^2004+1)
化简2cos2a-1/1-2sin2a
已知X＜-6,化简|1+|4-|2+X|||
化简（1）1!+2*2!+3*3!+…+12*12! （2）1/2！+2/3！+3/4！+…n/(n+1)!
化简:根号(1-根号3)^2
(2+1)(2^2+1)(2^4+1)~~~~~~(2^32+1)+1
(2+1)(2^2+1)(2^4+1)(2^8+1) +1
(2+1)(2^2+1)(2^4+1)....(2^64+1)+1
