j)1
Explicație pas cu pas:
f)
19-2²×[4×9:(3×2²)]=
19-4×[4×9:(3×4)]=
19-4×(4×9:12)=
19-4×(36:12)=
19-4×3=
19-12=7
g)
(3²-2³):(6²-7×5)=
(9-8):(36-35)=
1:1=1
h)
(4³-23⁰):3²+2²×8=
(64-1):9+4×8=
63:9+32=
7+32=39
i)(2²-3)¹⁰⁰+5:[3²
j)
21²-2×{11²+21:(2-1)+2×[1+2³×(1+2)+2⁴-2¹]}=
441-2×[121+21:1+2×(1+8×3+16-2)]=
441-2×[121+21+2×(1+24+16-2)]=
441-2×[121+21+2×(25+16-2)]=
441-2×[121+21+2×(41-2)]=
441-2×(121+21+2×39)=
441-2×(121+21+78)=
441-2×(142+78)=
441-2×220=
441-440=1
