  1. a) 96 – [ 456 – (32 – 12)^2 ]

    =96 – ( 456 – 20^2 )

    =96 – ( 456 – 400 )

    =96 – 56

    =40

    b) 32 : { 400 : [ 700 – ( 375 + 25 × 9)]}

    =32 : { 400 : [ 700 – ( 375 + 225 )]}

    =32 : [ 400 : ( 700 – 600 )]

    =32 : ( 400 : 100 )

    =32 : 4

    =8

    c) 5 –  :  + : 2^25

    =55 x 16 -18 : 9 + 32 x 2 097 152 : 33 554 432

    =880 – 2 + 2

    =880

    d) [ 545 – ( 45 + 4 × 25) ] : 50 – 5^3

    =( 545 -145 ) : 50 – 10^3 : 5^3

    = 400 : 50 – 1000 : 125

    = 8 – 8

    =0

    Cho ctlhn +5*+ cam on nha ! >< hihi

  2. Đáp án:

    a) 96 – [ 456 – (32 – 12)²}]

    = 96 – [456 – 20²]

    = 96 – [456 – 400]

    = 96 – 56

    = 40

    b) 32 : {400 : [700 – ( 375 + 25 × 9)]}

    = 32 : {400 : [700 – ( 375 + 225)]}

    = 32 : {400 : [700 – 600]}

    = 32 : {400 : 100}

    = 32 : 4

    = 8

    c) $5 x 4² – 18 : 3² + 2^{5} x 8^{7} : 2^{25}$

    $= 5 x 16 – 18 : 9 + 32 x 2097152 : 33554432$

    $= 80 – 2 + 67108864 : 33554432$

    $= 78 + 2$

    $= 80$

    d) $[545 – ( 45 + 4 × 25)] : 50 – 10³ : 5^{3}$

    $= [545 – ( 45 + 4 × 25)] : 50 – 1000 : 125$

    $= [545 – ( 45 + 100)] : 50 – 10³ : 5^{3}$

    $= [545 – 145] : 50 – 1000 : 125$

    $= 400 : 50 – 1000 : 125$

    $= 8 – 8$

    $=0$
