nho k cho minh nha

15164 nha bạn

1565+4+66+55+54914+4156+4-45600=15164

a,6312+4156

=104668

b,y=9640:8

y=1205

3156 x 2 + 4156 

\(\text{= 6312 + 4156 }\)

\(\text{= 10468}\)

\(\text{9640 : y = 8}\)

\(\text{y = 9640 : 8}\)

\(\text{y = 1205}\)

3156 x 2 + 4156 

=234 x 24+75x234x234x1

=234x(75+24+1)

=234x100

=23400

đề sai thì phải

a) (-24) + 18 + 24 + (-28)

= (-24 + 24) + (18 - 28)

= 0 - 28

= -28

b) (-32) . 234 + 234

= 234 . (-32 + 1)

= 234 . (-31)

= -7254

a, (-24) + 18 + 24 +(-28)

= (-24) + 24 - (28 - 18)

= 0 - 10

= - 10 

b, (-32) x 234 + 234

= - 234 x ( 32  - 1)

= -234 x 31

= - 7254 

a) (-24) + 18 + 24 + (-28)

= [(-24) + 24] + 18 + (-28)

= 0 + 18 + (-28)

= 18 + (-28)

= (-10)

b) (-32) x 234 + 234

= (-32) x 234 + 234 x 1

= 234 x (-32 + 1)

= 234 x (-31)

= (-7254)

a: \(\left(24-234\right)+\left(234-24-77\right)\)

\(=24-234+234-24-77\)

\(=\left(24-24\right)+\left(234-234\right)-77\)

=0+0-77

=-77

b: \(\left(13-135+49\right)-\left(13+49\right)\)

\(=13-135+49-13-49\)

\(=\left(13-13\right)+\left(49-49\right)-135\)

=0+0-135

=-135

c: \(159-524-\left(59-424\right)\)

\(=159-524-59+424\)

\(=\left(159-59\right)-\left(524-424\right)\)

=100-100

=0

d: \(\left(36+79\right)+\left(145-79-36\right)\)

\(=36+79+145-79-36\)

\(=\left(36-36\right)+\left(79-79\right)+145\)

=0+0+145

=145

e: \(334-\left(117+234\right)+\left(42+117\right)\)

\(=334-117-234+42+117\)

\(=\left(334-234\right)+\left(117-117\right)+42\)

=100+0+42

=142

f: \(271-\left[\left(-43\right)+271-\left(-17\right)\right]\)

\(=271+43-271+\left(-17\right)\)

\(=\left(271-271\right)+\left(43-17\right)\)

=0+26

=26

ai làm nhanh tui k cho ạ, giúp vs đang cần gấp

-234-(123-234)

= -234-123+234

= 123

\(a,-234-\left(123-234\right)\)

\(=-234-123+234\)

\(=-123\)

\(b,-24.33+40.24+13.30+13.46\)

\(=24\left(-33+40\right)+13\left(30+46\right)\)

\(=24.13+13.76\)

\(=13.\left(24+76\right)\)

\(=13.100=1300\)

\(c,34.\left(-84\right)+17.\left(-32\right)\)

\(=17.2.\left(-84\right)+17.\left(-32\right)\)

\(=17.\left(-168-32\right)\)

\(=17.\left(-200\right)\)

\(=-3400\)

234 x 24 + 75 x 234 + 234 = 234 x (24 + 75 + 1) = 234 x 100 = 23400

135 x 111 - 1350 - 13500 = 135 x 111 - 135 x 10 - 135 x 100 = 135 x (111 - 10 - 100) = 135 x 1 = 135

4156 chỉ 5 chục, 5982 chỉ 5 nghìn, 1945 chỉ 5 đv

Trong 4156 chỉ : 50

Trong 5982 chỉ : 5000

Trong 1945 chỉ : 5

4156 chỉ : 50
