Răspuns:
a) (4+3)³-(4-3)¹⁰=7³-1¹⁰=343-1=342
b) (10³-125·2³):123¹²³=(10³-5³·2³):123¹²³=(10³-10³):123¹²³=0³:123¹²³=0
c) [(10³:5²:8+3²·5²)):3⁰]·[tex]2^{2^{0} }[/tex]=[(2³·5³:5²:2³+15²):1]·2=(5+225)·2=230·2=460
d) {[(12²+5²):13]²-2⁷-2⁰}:2³={[(144+25):13]²-128-1}:8=[(169:13)²-129]:8=
=(13²-129):8=(169-129):8=40:8=5
