问题 (32+1)(812+1)(92+1)(32-1)=
选项 A、814+1
B、99-1
C、316-1
D、332-1
E、396+1
答案C
解析 This question at first appears to be a monster, but you can simplify the statements by reordering them and stating all of the exponential numbers as powers of 3: (32-1)(32+1)(34+1)(38+1). Then, you can scan through the answers and realize that 316-1=(38+1)(38-1)=(38+1)(34+1)(34-1)=(38+1)(34+1)(32+1)(32-1), which is the same as the statement in the question.
