Đáp án:

a) 0

b) 100

c) 23

d) 2013

Giải thích các bước giải:

a) 17 × 64 + 17 × 36 – 1700 = 17 × 64 + 17 × 36  – 17 × 100 = 17 × ( 64 + 36 – 100 ) = 17 × 0 = 0

b) ( -46 ) + 81 + ( -64 ) + ( -91 ) – ( -220 ) = { ( -46 ) + ( -64 ) } + { 81 + ( -91 ) } – ( -220) 

= ( -110 ) + ( -10 ) – ( -220 ) = – ( 110 + 10 – 220 ) = 100

c)  2³ × $3^{1}$ – ( $1^{2012}$ + $2012^{0}$ ) : l -2 l = 8 × 3 – ( 1 + 1 ) : 2 = 24 – 2 : 2 = 24 – 1 = 23

d) { 47-[ 736 : ( 5 – 3 ) ^ 4] } × 2013 =  { 47-[ 736 : ( $2^{4}$ ] } × 2013

= { 47 – [ 736 : 16 ] } × 2013 = { 47 – 46 } × 2013 = 1 × 2013 = 2013
