解答题
化简:(2+1)(22+1)(24+1)(28+1)+1.
答案
(2+1)(22+1)(24+1)(28+1)+1,
=(2-1)(2+1)(22+1)(24+1)(28+1)+1,
=(22-1)(22+1)(24+1)(28+1)+1,
=(24-1)(24+1)(28+1)+1,
=(28-1)(28+1)+1,
=216-1+1,
=216.
化简:(2+1)(22+1)(24+1)(28+1)+1.
(2+1)(22+1)(24+1)(28+1)+1,
=(2-1)(2+1)(22+1)(24+1)(28+1)+1,
=(22-1)(22+1)(24+1)(28+1)+1,
=(24-1)(24+1)(28+1)+1,
=(28-1)(28+1)+1,
=216-1+1,
=216.
