1. a) 9³-3⁴=729-81=648

b) 2012¹+1²⁰¹²=2012+1=2013

c) 25⁰• 0²⁵=0

d) (5-2)³=3³=27

2. a) 16²⁸>14²⁸

b)25¹²³<25²²³

c)16¹⁴ < 8²¹

d)25²⁵< 5⁴⁸

3. a) 12³⁴:12³²-3¹•3²+2³=12³⁴-³²-3¹+²+2³=12²-3³+2³=24-27+8=(facem 24+8(factorul comun)) 24+8-27=32-27=5

b)2³•3²+25⁰•11²-4⁰=8•9+0•121-0=72+0-0=72

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)•4-3]+2=9•[(8+77)•4-3]+2=9•(85•4-3)+2=9•(340-3)+2=9•337+2=3033+2=3035
