Repede v rog dau corona!!!!!!​

Answer 1

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
