Các bạn giải từng cách ra nha

Câu 1 :

a) 25 - (-75) + 32 - (32 + 75)

= 25 + 75  + 32 - 32 - 75

= 25 + (75 - 75) + (32 - 32)

= 25 + 0 + 0

= 25

b) |-127| - 18 . (5  - 6)

= 127 - 18 . (-1)

= 127 + 18

= 145

c) 24.(16 - 5) - 16.(24 - 5)

= 24.11 - 16.19

= 16.16,5 - 16.19

= 16.(16,5 - 19)

= 16.(-2,5)

= -40

ủng hộ tớ nha

kb nha

a)25-(-75)+32-(32+75)=25-(-75)+32-107=25

b)l-127l-18.(5-6)=127-18.(-1)=127-(-18)=145

c)24.(16-5)-16.(24-15)=24.11-16.9=264-144=120

a) ( - 78 ) . ( 1 + 187 ) + 187 . 78

= ( - 78 ) + ( - 78 ) . 187 + 187 . 78

= ( - 78 ) + 187 . [ ( - 78 ) + 78 ]

= ( - 78 ) + 187 . 0

= ( - 78 ) + 0

= ( - 78 )

b) ( - 39 ) . 15 - 36 . 39 - 49 . ( - 39 )

= ( - 39 ) . 15 + 36 . ( - 39 ) - 49 . ( - 39 )

= ( - 39 ) . ( 15 + 36 - 49 )

= ( - 39 ) . 2

= - 78

a) (-78).(1+187) + 187.78 = -78 - 78.187 +187.78 = -78

b) (-39).15 - 36.39 - 49.(-39)

= -39.15 - 36.39 + 49.39

=39.(-15-36+49)

= 39.(-2)

= - 78

Tích mk nha !!!!~~

a,\(25-\left(-75\right)+32-\left(32+75\right)\))

=\(25+75+32-32-75\)

=\(\left(75-75\right)+\left(32-32\right)+25\)

=\(0+0+25=25\)

\(b,\left|-127\right|-18.\left(5-6\right)\)

\(=127-18.\left(-1\right)\)

\(=127-\left(-18\right)\)

\(=145\)

\(c,17-25+55-17\)

\(=\left(17-17\right)+\left(55-25\right)\)

\(=0+30\)

\(=30\)

a)

25 - (-75) + 32 - ( 32 + 75 )

= 25 + 75 + 32 - 107

=100+32 - 107

=132 - 107

=25
