Răspuns:
[tex]$\mathbf{ \frac{8}{3} }$[/tex]
Explicație pas cu pas:
[tex]$\mathbf{ | - 1.(3)| + |2.(6) - 4| }$[/tex]
[tex]$\mathbf{1.(3) = \frac{13 - 1}{9} = \frac{12}{9} {}^{(3} = \frac{4}{3} }$[/tex]
[tex]$\mathbf{2.(6) = \frac{26 - 2}{9} = \frac{24}{9} {}^{(3} = \frac{8}{3} }$[/tex]
[tex]$\mathbf{ | - \frac{4}{3} | + | \frac{8}{3} - 4 | = | - \frac{4}{3} | + | - \frac{4}{3} | }$[/tex]
[tex]\boxed{modului \: unui \: nr \: este \: mereu \: pozitiv}[/tex]
[tex]$\mathbf{ \frac{4}{3} + \frac{4}{3} = \frac{8}{3} }$[/tex]
Bafta!
