1997-[10.(56-4^3):2^3+2^3)].1
= 1997-[10.(56-64):8+8)].1
= 1997-[10.(-8):8+8].1
= 1997-[(-80):8+8].1
= 1997-[(-10)+8].1
= 1997-(-2).1
= 1997-(-2)
= 1997+2
= 1999

Giải đáp+Lời giải và giải thích chi tiết:
1977 – [10. ( 56 – 4³ ) : $2^{3+2}$ + 2³] . 1
= 1977 – [ 10. ( 56 – 64 ) : $2^{5}$ + 2³] .1
= 1977 – [ 10 .( -8) : 32 + 8 ] .1
= 1977 – [ – 80 : 40 ] .1
= 1977 – (-2) . 1
= 1977 – (-2)
= 1979
