= 1024 

TICK NHA !

Answer 2

1024 Tick nha

Answer 3

=(20/10).(18/9).(16/8).(14/7).(12/6).(10/5).(8/4).(6./3).(4/2).(2/1)

=2.2.2.2.2.2.2.2.2.2

=2¹⁰

=1024

tick nha bạn

Answer 4

(2.4.6.8.10.12.14.16.18.20):(1.2.3.4.5.6.7.8.9.10)

=(2:1).(4:2).(6:3).(8:4).(10:5).(12:6).(14:7).(16:8).(18:9).(20:10)

=2.2.2.2.2.2.2.2.2.2=1024

Answer 5

(2.4.6.8.10.12.14.16.18.20)/(1.2.3.4.5.6.7.8.9.10)

=(2/1).(4/2).(6/3).(8/4).(10/5).(12/6).(14/7).(16/8).(18/9).(20/10)

2.2.2.2.2.2.2.2.2.2=1024

Answer 6

(2 . 4 . 6 . 8 . 10 . 12 . 14 . 16 . 18 . 20) : (1 . 2 . 3 . 4 . 5 . 6 . 7 . 8 . 9 . 10) = (2 : 1) . (4 : 2) . (6 : 3) . (8 : 4) . (10 : 5) . (12 : 6) . (14 : 7) . (16 : 8) . (20 : 10)

= 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 = 2¹⁰ = 1024
