2 . 4 + 5. 2 + 2. 6 + 2 . 3 + 2 . 2
= 2 . ( 4 + 5 + 6 + 3 + 2 )
= 2 . 20
= 40
2 . 4 + 5. 2 + 2. 6 + 2 . 3 + 2 . 2
= 2.(4+5+6+3+2)
= 2. 20
= 40
2 . 4 + 5. 2 + 2. 6 + 2 . 3 + 2 . 2
= 2. (4 + 5 + 6 + 3 + 2)
= 2 . 20
= 40
2.4+5.2+2.6+2.3+2.2
=2.(4+5+6+3+2)
=2.20
=40
2 x 4 + 5 x 2 + 2 x 6 + 2 x 3 + 2 x 2
= 2 x ( 4 + 5 + 6 + 3 + 2 )
= 2 x 20
= 40.
2 . 4 + 5 . 2 + 2 . 6 + 2 . 3 + 2 . 2
= 2 x ( 4 + 5 + 2 + 6 + 3 )
= 2 x 20
= 40
đúng không ?
