Question

\(\left|x-2,6\right|+\left|0,7-x\right|=0\)

Answer 1

(left|x-2,6 ight|+left|0,7-x ight|ge0)

Dấu "=" xảy ra khi:

(left{{}egin{matrix}left|x-2,6 ight|=0\left|0,7-x ight|=0end{matrix} ight.Leftrightarrowleft{{}egin{matrix}x=2,6\x=0,7end{matrix} ight.)

Vì (2,6 e0,7Leftrightarrow xinvarnothing)
