(3+1)(3*2+1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)简便计算,
(3+1)(3*2+1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)简便计算,
(3+1)(3*2+1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)简便计算,
(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)
=2(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)/2
=(3-1)(3+1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)/2
=(3^2-1)(3^2+1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)/2
=(3^4-1)(3^4+1)(3^8+1)(3^16+1)(3^32+1)/2
=(3^8-1)(3^8+1)(3^16+1)(3^32+1)/2
=(3^16-1)(3^16+1)(3^32+1)/2
=(3^32-1)(2^32+1)/2
=(3^64-1)/2
你那个是乘方吧
(3+1)(3*2+1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)
=﹙3-1)(3+1)(3*2+1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)/﹙3-1﹚
=½×[﹙3²-1)(3*2+1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)]
=½×[﹙3^4-1)(3*4+1)(3*8+1)(3*16+1)(3*32+1)]
=······
=½×﹙3^64-1﹚
