\(=\left[76\times\left(35+19\right)\right]:54\)

\(=\left[76\times54\right]:54\)

\(=76\times54:54\)

\(=76\times\left(54:54\right)\)

Lời giải 

\(=\left[76.\left(35+19\right)\right]:54\)

\(=\left[76.54\right]:54\)

\(=4104:54\)

\(=76\)

a) -2112

b) 1542

c) 1007

tính nhanh mà bn kết quả thì mk bít rùi mk cần cách làm cơ

tick di rùi đây giải cho

a)  -2112

b) -2432

c)  1007

d)  944

e) 72

f)  -1871

\(-54.76+12.\left(-76\right)-76.\left(-34\right)\)

\(=54.\left(-76\right)+12.\left(-76\right)-\left(-76\right).34\)

\(=-76.\left(54+12-34\right)\)

\(=-76.32\)

\(=-2432\)

-54*76+12*(-76)-76*(-34)

=(-4104)+(-912)-(-2584)

=-2429

k cho mk nhé

b) 35 x 24 + 35 x 76 +55 x 19 +55 x 91

= 35 x ( 24 + 76 ) + 55 x ( 19 + 91 )

= 35 x100 +55 x 100

= 100 x ( 55 + 35 )

= 90 x 100 =9 000

c) \(6\cdot25\cdot4+4\cdot19\cdot6-2\cdot14\cdot12\)

\(=24\cdot25+24\cdot19-24\cdot14\)

\(=24\left(25+19-14\right)\)

\(=24\cdot30=720\)

d) \(19\cdot64+76\cdot34\)

\(=76\cdot19+76\cdot34\)

\(=76\left(19+34\right)=76\cdot53=4028\)

a) 2 x 16 x 50 x 25

= ( 2 x 50 ) x ( 16 x 25 )

= 100 x 400 

= 40 000
