= 6,25+1,2·[11+1,1·(6,5+2·0,05)]

=6,25+1,2·[11+1,1·(6,5+0,1)]

=6,25+1,2·(11+1,1·6,6)

=6,25+1,2·(11+7,26)

=6,25+1,2·18,26

=6,25+21,912

=28,162

Explicație pas cu pas:

[tex]2,5^{2}+1,2\cdot\{11+1,1\cdot[6,5+2\cdot(8,65-8,6)]\}=[/tex]

[tex]6,25+1,2\cdot\{11+1,1\cdot[6,5+2\cdot(8,65-8,6)]\}=[/tex]

[tex]6,25+1,2\cdot[11+1,1\cdot(6,5+2\cdot0,05)]=[/tex]

[tex]6,25+1,2\cdot[11+1,1\cdot(6,5+0,1)]=[/tex]

[tex]6,25+1,2\cdot(11+1,1\cdot6,6)=[/tex]

[tex]6,25+1,2\cdot(11+7,26)=6,25+1,2\cdot18,26=[/tex]

[tex]6,25+21,912=\boxed{28,162}[/tex]
