Question

ính theo cách hợp lý:

 \(46\times182-23\times72-92\times23\)

giúp mình nha!

Answer 1

46 x 182 - 23 x 72 - 92 x 23

= (23 x 2) x 182 - 23 x 72 - 92 x 23

= 23 x (2 x 182) - 23 x 72 - 92 x 23

= 23 x 364 - 23 x 72 - 92 x 23

= 23 x (364 - 72 - 92)

= 23 x 200

= 4600

Answer 2

46x 182 - 23 x 72 - 92 x 23

= 46 x 182 - 23 x 2 x 36 - 46 x 2 x 23

= 46 x 182 - 46 x 36 - 46 x 46

= 46 x ( 182 - 36 - 46 )

= 46 x 100

= 4600

k mình nhee

Answer 3

= 4600 nha !!!
