+) 477x6+2x[72: 8+5x160–(4x200: 2–45: 3)=ma ajutati va rog​

Răspuns:

Explicație pas cu pas:

477 x 6 + 2 x [ 72 : 8 + 5 x 160  - ( 4 x 200 : 2 - 45: 3 ) ]=

477 x 6 + 2 x [ 72 : 8 + 5 x 160 - ( 800 : 2 - 15 ) ] =

477 x 6 + 2 x [ 72 : 8 + 5 x 160 - ( 400 - 15 ) =

477 x 6 + 2 x ( 72 : 8 + 5 x 160 - 385 ) =

477 x 6 + 2 x ( 9 + 800 - 385 ) =

477 x 6 + 2 x ( 809 - 385 ) =

477 x 6 + 2 x 424=

2862 + 848 =

3710

477 × 6 + 2 × [ 72 : 8 + 5 × 160 - ( 4 × 200 : 2 - 45 : 3 ) ] =

2862 + 2 × [ 9 + 800 - ( 800 : 2 - 15 ) ] =

2862 + 2 × [ 809 - ( 400 - 15 ) ] =

2862 + 2 × ( 809 - 385 ) =

2862 + 2 × 424 =

2862 + 848 = 3710
