(19-45:(570-565))*inmultire*409=(19-45:45)*inmultire*409=(19-9)*inmultire*409=10*inmultire*409=4090. am scris *inmultire* pt. ca nu gaseam semnul pe tastatura

Answer 2

   

[133 : 7 - 45 : (57 × 10 -565)] × 409 =

= [133 : 7 - 45 : (570 -565)] × 409 =

= [133 : 7 - 45 : 5] × 409 =

= [19  - 9] × 409 =
