单选题If x=1/4, then which of the following has the greatest value?AxB1/(2x)Cx2D1-xEx3

单选题
If x=1/4, then which of the following has the greatest value?
A

x

B

1/(2x)

C

x2

D

1-x

E

x3


参考解析

解析:
如果x = 1/4,那么A为1/4;B为1/(2×4)=1/8;C为(1/4) ×(1/4)=1/16;D为1- (1/4)=3/4;E为(1/4) ×(1/4) ×(1/4) =1/64。所以D的值最大。
