Question

Thực hiện phép tính

80:{51-[18-(2².3-5)]}

Answer 1

Bằng 2 nha bạn 

Answer 2

80 : {51 - [18 - (2² . 3 - 5)]}

= 80 : {51 - [18 - 7]}

= 80 : {51 - 11}

= 80 : 40

= 2

Answer 3

80 : { 51 - [ 18 - ( 2² . 3 - 5 ) ] }

= 80 : { 51 - [ 18 - ( 4 . 3 - 5 ) ] }

= 80 : { 51 - [ 18 - 7 ] }

= 80 : { 51 - 11 }

= 80 : 40

= 2

Answer 4

80 : {51 - [18 - (2² . 3 - 5)]}

= 80 : {51 - [18 - (4 . 3 - 5)]}

= 80 : {51 - [18 - 7]}

= 80 : {51 - 11}

= 80 : 40

= 2

Answer 5

80:{51-[18-(2².3-5)}

= 80:{51-[18-7]}

= 80:{51-11}

= 80:40 = 2

Answer 6

80 : { 51 - [18 - ( 2² . 3 - 5 )]}

= 80 : { 51 - [ 18 - ( 4 . 3 - 5 )]} 

= 80 : { 51 - [ 18 - 7 ]}

= 80 : { 51 - 11 )

= 80 : 40

= 2 

Answer 7

80:{51-[18-(2².3-5)]}

= 80:{51-[18-(4.3-5)]}

= 80:{51-[18-7]}

= 80:{51-11}

= 80:40
