a) 12³⁴:12³²-3¹•3²+2³=179
=12²-3³+8
=144-27+8
=179
b)2³•3²+25⁰•11²-4⁰=194
=8•9+1•121-1
=72+121-1
=194
c) 1+{2+[3•(4+5)-6+7•8]-9}=71
=1+{2+[3•9]-6+56]-9}
=1+{2+[27-6+56]-9}
=1+{2+77-9}
=1+70
=71
d)9•{[8+7•(6+5)]•4-3}+2=3 035
=9•{[8+7•11]•4-3}+2
=9•{[8+77]•4-3}+2
=9•{85•4-3}+2
=9•{340-3}+2
=9•337+2
=3 033+2
=3 035
Cu plăcere!!!
