48 x 27 + 48 + 96 x 36
= 48 x (27 + 1) + 48 x 72
= 48 x 28 + 48 x 72
= 48 x (28 + 72)
= 48 x 100
= 4800 .

bằng 4800

ta lay 72÷36

A = \(\dfrac{8\times12\times32+4\times27\times24+96\times41}{16\times48-48\times9+4\times3\times12}\)

A = \(\dfrac{96\times32+96\times27+96\times41}{16\times48-48\times9+48\times3}\)

A = \(\dfrac{96\times\left(32+27+41\right)}{48\times\left(16-9+3\right)}\)

A = \(\dfrac{96\times100}{48\times10}\)

A = \(\dfrac{20}{1}\) \(\times\) \(\dfrac{48\times10}{48\times10}\)

A = 20 

chịu haizz

cái nào dễ thì làm khó bỏ đi nhé

thì bn hỏi làm j

1

so dau o thung be la

(208 - 60):2=74(lit)

so dau o thung lon la

208 - 74 = 134(lit)

2

48 x 27 + 48 + 96 x 36

=48 x 27 + 48 + 48 x 2 x 36

=48 x (27 + 1 + 72)

= 48 x 100 = 4800

Bài 1 :

Thùng lớn là :

208 - 60 = 148 (l)

Thùng bé là :

208 - 148 = 60 (l) 

Đáp số : ..................

A) 4,29 x 1230 - 429 x 2,3

= 429 x 12,3 - 429 x 2,3

= 429 x ( 12,3 - 2,3 )

= 429 x 10

= 4290

B) 30 - 15 + 36 - 18 + 42 - 21 + ... + 96 - 48 + 102 - 51

= ( 15 + 15 ) - 15 + ( 18 + 18 ) - 18 + ... + ( 48 + 48 ) - 48 + ( 51 + 51 ) - 51

= 15 + 18 + 21 + ... + 48 + 51

= [( 51 - 15 ) : 3 + 1] x ( 15 + 51 ) : 2

= [36 : 3 + 1] x 66 : 2

= [12 + 1] x 33

= 13 x 33

= 429

bạn nào giúp mình vs

a) x = 25 ;26 

b) x = 0;1;2;3;4;...........;28;2930

c) x= 82; 83;84;85;86;87;88;89;90;91;92;93

d) x = 92

x = 25 ; 26

x = 0 ; 1 ; 2 ; ... ; 30

x = 82 ; ... ; 92

x = 92

24 < x < 27

=> x = 24, 25 , 26

Ta có: \(13\cdot\left(-47\right)-53\cdot13\)

\(=13\cdot\left(-47-53\right)\)

\(=13\cdot\left(-100\right)=-1300\)

Ta có: \(27\cdot\left(-67\right)+33\cdot\left(-27\right)\)

\(=27\cdot\left(-67\right)-33\cdot27\)

\(=27\left(-67-33\right)\)

\(=27\cdot\left(-100\right)=-2700\)

Ta có: \(-49\cdot65+36\cdot\left(-49\right)+49\)

\(=-49\cdot65+\left(-49\right)\cdot36+\left(-49\right)\cdot\left(-1\right)\)

\(=-49\cdot\left(65+36-1\right)\)

\(=-49\cdot100=-4900\)

Ta có: \(136\cdot\left(-47\right)+36\cdot47\)

\(=\left(-136\right)\cdot47+36\cdot47\)

\(=47\cdot\left(-136+36\right)\)

\(=47\cdot\left(-100\right)=-4700\)

Ta có: \(\left(-48\right)\cdot72+36\cdot\left(-304\right)\)

\(=-96\cdot36+36\cdot\left(-304\right)\)

\(=36\cdot\left(-96-304\right)\)

\(=36\cdot\left(-400\right)=-14400\)
