\(58\times57+58\times50-58\times25=58\times\left(57+50-25\right)=4756\)

58 × 57 + 58 × 50 - 58 × 25

= 58 × (57 + 50 - 25)

= 58 × 82

= 4756

58 x 57 + 58 x 50-58 x 25

= 3306 + 2900 - 1450

= 4756

=17,58 * (43+57)

=17,58 * 100

=1758

cảm ơn cậu

\(\left(100+42\right).42+\left(200-58\right).58\)

\(=142.42+142.58\)

\(=142.\left(42+58\right)\)

\(=142.100\)

\(=14200\)

k nha

Kết quả = 14200 nha

(100 + 42 ).42 + 58(200 - 58)

= 142.42 + 58.142

= 142.(42 + 58)

= 142.100

= 14200

các bạn giải nhanh giúp mình với!

cảm ơn bạn nhiều nhé

( 100 + 42 ) x 42 + ( 200 - 58 ) x 58

= 142 x 42 + 142 x 58

= 142 x ( 42 + 58 )

= 142 x 100

= 14200

58x42+32x58+74x42

= 58x ( 42+ 32 ) + 74 x 42

=58 x 74 + 74 x 42

= 74 x ( 58+ 42)

=74 x 100

=7 400

58.(42+32)+74.42=58.74+74.42=74.(58+42)=74.100=7400

42.(58 - 11) - 58.(11 + 42)

= 42.58 - 42.11 - 58.11 - 58.42

= 42.58 - 58.42 - 42.11 - 58.11

= -11.(42 + 58)

= -11. 100

= -1100

mk ghi kết quả thui nhé = -1100

-1100 nha 

ung ho nhe

(100+42) x42+(200-58)x58

=142x42+142x58

=142x(42+58)

=142x100

=14200

\(\left(100+42\right)\times42+\left(200-58\right)\times58\)

\(=142\times42+142\times58\)

\(=142\times\left(42+58\right)\)

\(=142\times100=14200\)

142 x 42 + 142 x 58

= 142 x (42 +58)

=142 X 100

=14200

237*100-137*100

23700-13700

10000

\(237.\left(42+58\right)-137.\left(58+42\right)\)

\(=237.100-137.100\)

\(=100.\left(237-137\right)\)

\(=100.100=10000\)
