Answer 1

Tính nhanh :

165 x 23 - 65 x 23

= 23 x ( 165 - 65 )

= 23 x 100

= 2300                    

136 + 63 + 100

= 199 + 100

= 299                     

165 -20 - 65

= ( 165 - 65 ) - 20

= 100 - 20

= 80

Answer 2

165 x 23 - 65 x 23 = ( 165 - 65 ) x 23 = 100 x 23 = 2300

136 + 63 + 100 = 199 + 100 = 299

165 - 20 - 65 = 165 - 65 - 20 = 100 - 20 = 80

Answer 3

165 x 23 - 65 x 23 

= ( 165 - 65 ) x 23

= 100 x 23

= 2300

      136 + 63 + 100

    = 199 + 100

    = 299

165 - 20 - 65

= ( 165 - 65 ) - 20

= 100 - 20 

= 80
