Question

1997-[10 . (2^3-56):2^3+2^3] . 2005 Giúp tớ với ạ

Answer 1

\(1997-\left[10.\left(2^3-56\right):2^3+2^3\right].2005\)

\(=1997-\left[10.\left(8-56\right):8+8\right].2005\)

\(=1997-\left[10.\left(-48\right):8+8\right].2005\)

\(=1997-\left[\left(-60\right)+8\right].2005\)

\(=1997-\left(-52\right).2005\)

\(=1997-\left(-104260\right)=106257\)

Answer 2

1997-[10.(2³- 56): 2³+2³ ].2005

= 1997-[10.(8 - 56): 2³+2³ ].2005

= 1997-[10.(-48): 2³+2³ ].2005

= 1997-[10.(-48): 8 + 8 ].2005

= 1997-(-52).2005

= 106257
