Answer 1

Răspuns:

6+2[(3·5²-2²·18:3²+3·11):2²]=

6+2[(3·25-4·18:9+3·11):4]=

6+2[(75-8+33):4]=

6+2(100:4)=

6+2·25=

6+50=

Answer 2

Răspuns: $\bf \red{\underline{~56~}}$  

$\bf 6 + 2 \cdot [(3 \cdot 5^2 - 2^2 \cdot 18 : 3^2 + 3 \cdot 11) : 2^2] =$

$\bf 6 + 2 \cdot [(3 \cdot 25 - 4 \cdot 18 : 9 + 3 \cdot 11) : 4] =$

$\bf 6 + 2 \cdot [(75 - 72 : 9 + 33) : 4] =$

$\bf 6 + 2 \cdot [(75 - 8 + 33) : 4] =$

$\bf 6 + 2 \cdot [(67 + 33) : 4] =$

$\bf 6 + 2 \cdot (100 : 4) =$

$\bf 6 + 2 \cdot 25 =$

$\bf 6 + 50 =$

$\bf \red{\underline{~56~}}$
