a/=36.(28+82)+64.(69+41)

=36.110+64.110=110.(36+64)=110.100=11000

a) kết quả là:2400

b)Kết quả là: 11000

Đáp số: 11000

a) 2 x 31 x 12 + 4 x 6 x 42 + 8 x 27 x 3

  = 24 x 31 + 24 x 42 + 24 x 27

  = 744 + 1008 + 648

  = 2400

b) 36 x 28 + 36 x 82 + 64 x 69 + 64 x 41

    = 36 x (28 + 82) + 64 x (69 + 41)

    = 36 x 110 + 64 x 110

    = (36 + 64) x 110

     = 100 x 110

     = 11000

a) 2400

b) 11000

Kết quả

a) = 2400

b) = 11000

a)=24.31+24.42+24.27=24.(31+42+27)=24.100=2400

b)=36.(28+82)+64.(69+41)=36.110+64.110=110.(36+64)=110.100=11000

a) 2.31.12 + 4.6.42 + 8.27.3 = 24.31 + 24.42 + 24.27 = 24.(31 + 42 + 27) = 24.100 = 2400

b) 36.28 + 36.82 + 64.69 + 64.41

= 36.(28 + 82) + 64.(69 + 41)

= 36. 110 + 64. 110

= 110. (36 + 64) = 110.100 = 11000

a ) = 24 . 31 + 24.42 + 24.27

= 24 . ( 31+42+27)

=24.100

= 2400

b) = 36.( 28+82) + 64.( 69+41)

= 36.101 + 64.101

=101.( 36+64)

=101.100

=10100

sai rồi kết quả là 11000 chứ

a) 2.31.12+4.6.42+8.27.3

=24.31+24.42+24.27

=24.(31+42+27)

=24.100

=2400

b) 36.28+36.82+64.69+64.41

=36.(28+82)+64.(69+41)

=36.110+64.110

=110.(36+64)

=110.100

=11000

trieu dang trả lời đúng rùi cho bạn ấy 1 cái đúng nhé

2.31.12+4.6.42+8.27.3

=24.31+24.42+24.27

=24.(31+42+27)

=24.100

=2400

36.28+36.82+64.69+64.41

=36.(28+82)+64.(69+41)

=36.100+64.100

=(36+64).100

=100.100

=10000

a)\(2.31.12+4.6.42+8.27.3\)

\(=24.31+24.42+24.27\)

\(=24.\left(31+42+27\right)\)

\(=24.100\)

\(=2400\)

b)\(36.28+38.82+64.69+64.41\)

\(=36.\left(28+82\right)+64.\left(69+41\right)\)

\(=36.110+64.110\)

\(=110.\left(36+64\right)\)

\(=110.100\)

\(=11000\)
