Given m is a real number,and|1-m|=|m|+1,simplify an algebraic expression,then√m^2-2m+1=
A |m|-1 B -|m|-1 C m-1 D-m+1

Given m is a real number,and|1-m|=|m|+1,simplify an algebraic expression,then√m^2-2m+1=A |m|-1 B -|m|-1 C m-1 D-m+1
D
|1-m|=|m|+1得m=<0

由于M是实数,且| 1米| = |常年 1 ,简化代数式,然后√平方公尺- 2 +1 =
|普通| -1 B组-|公| - 1c的M - 1个D米+ 1
