47 x 2 94         25 x 3 75         16 x 6 96         18 x 4 72 28 x 6 168         36 x 4 144         82 x 5 410         99 x 3 297

125 - 60 : 6 : 5 x 7 - 16 x 3

= 125 - 10 : 5 x 7 - 48

= 125 - 2 x 7 - 48

= 125 - 14 - 48

= 111 - 48

= 63

125 - 60 / 6 / 5 *7 - 16 * 3 = 125 - 14 - 16 = 95 

( 485 + 3) x 8 x ( 2 x12 - 2x7 - 2x5 )

=( 485 + 3) x 8 x [2 x ( 12 -7-5)]

= ( 485 + 3) x8 x(2x0)

= (485 + 3) x8 x0

= (485 +3) x0

96:(y:6)=96:(2x12)

96:(y:6)=(2x12)

96:(y:6)=24

y:6=96:24

y:6=4

tick nha

12 x 3 + 12 x 4 + 12 x 5 + 12 x 6

= 12 x ( 3+4+5+6)

= 12 x 18 = 216

12x3+12x4+12x5+12x6=12x(3+4+5+6)=12x18=216

23×2 = 46

12x3 = 36

12x4 = 48

Trả lời:

12x3+4x12+36 = 12(3+4+3)= 12x10= 120

12x3+4x12+12x3                                                                                                      

=12x(3+4+3)

=12x10
