\(a.132-\left[116-4^2\right]\) \(c.120:\left\{300:\left[150-\left(2.125-8.25\right)\right]\right\}\)
= \(132-\left[116-16\right]\) = \(120:\left\{300:\left[150-\left(250-200\right)\right]\right\}\)
= \(132-100\) = \(120:\left\{300:\left[150-50\right]\right\}\)
= \(32\) = \(120:\left\{300:100\right\}\)
= \(120:3\)
= \(40\)
132 - [ 116 - ( 132 - 128 )2 ] { 46 - [( 16 + 71 , 4 ) : 15 ]} -2 Ý cuối cùng mình làm luôn cứ thế mà
= 132 - [ 116 - 16 ] = { 46 - [ 87,4 : 15] } - 2 chép.
=132 - 100 = { 46 - 5,8266 } - 2 = 120 : { 300 : [ 150 - ( 210 - 200) ]}
= 32 = 40,1734 - 2 = 120 : { 300 : [ 150 - 10 ]}
=38,1734m = 120 : { 300 : 140 }
= 120 : 2,1428
