a) \(36.\left(-57\right)-57.64\)
\(=36.\left(-57\right)+\left(-57\right).64=\left(-57\right).\left(36+64\right)\)
\(=\left(-57\right).100=-5700\)
b)\(32.\left(-17\right)+\left(-18\right).17-50.13\)
\(=\left(-32\right).17+\left(-18\right).17-50.13\)
\(=17.\left(-32-18\right)-50.13=17.\left(-50\right)+\left(-50\right).13\)
\(=\left(-50\right).\left(17+13\right)=\left(-50\right).30=-150\)

Chúc em học tốt!!!!!!
1 . (15+37)+(52-37-17)
= 15+37+52-37-17
=(15-17)+(37-37)+52
= -2+0+52 = 50
2. (27+65)+(346-27-65)
= 27+65+346-27-65
=(27-27)+(65-65)+346
=0+0+346
=346
a) 46 + 17 + 54 = 117
b) 4 . 37 . 25 = 3700
c) 87. 36 + 87 . 64 = 8700
kick mik đi
a, ( 46 + 54 ) + 17 = 100 + 17 = 117
b, ( 4 . 25 ) . 37 = 100 . 37 = 3700
c, 87 . ( 36 + 64 ) = 87 . 100 = 8700
a,46+17+54
=(46+54)+17
=100+17
=117
b,4.37.25
=(4.25).37
=100.37
=3700
c,87.36+87.64
=87.(36+64)
=87.100
=8700
Chúc bạn học giỏi nha ^-^
a ) 5 x 216 x 25 x 4 = 1080 x 100 = 108000
b ) 37 x 16 x 25 x 4 = 592 x 100 = 59200
c ) 36 x ( 28 + 82 ) + 64 x ( 69 + 41 ) = 36 x 110 + 64 x 110 = ( 36 + 64 ) x 110 = 100 x 110 = 11000

Mik nhanh nhất đấy , nhớ click cho mik nha !!!!!!!!!!!!!!!!!!!
a) 5 x 25 x 216 x 4
= ( 5 x 216 ) x ( 25 x 4 )
= 1080 x 100
= 108000

= ( 4 x 25 ) x ( 37 x 16 )
= 100 x 592

k mk nhá
a)5*25*216*4=(25*4)*(5*216)=100*1080=108000
b)4*37*25*16=(4*25)*(37*16)=100*592=59200
c)36*28+36*82+64*69+64*41=36*(28+82)+64*(69+41)=36*110+64*110=110*(36+64)=110*100=11000

h)17+17*81+18*17=17*(1+81+17)=17*100=1700
( 4*25 ) * ( 5*216)
= 100 * 1080
= 108000
