Raspuns:
a. 125
b. 192
c. 71
d. 767
Explicație pas cu pas:
a. 12³⁴:12³²-3¹×3²+2³=
12²-3³+8=
144-27+8=
117+8=125
b. 2³×3²+25⁰×11²-4⁰=
8×9+1×121-1=
72+121-1=
72-120=192
c. 1+{2+[3×(4+5)-6+7×8]-9}=
1+[2+(3×9-6+56)-9]=
1+[2+(27-6+56)-9]=
1+[2+(21+56)-9]=
1+(2+77-9)=
1+(79-9)=
1+70=71
d. 9×{[8+7×(6+5)]×4-3}+2=
9×[(8+7×11)×1]+2=
9×[(8+77)×1]+2=
9×(85×1)+2=
9×85+2=
765+2=767
