a] 7.3+(6+2.(2³:4+3.2)-7.√1)+9:3 =

 7.3 + (6 + 2. (8:4 + 3.2) - 7.√1) + 9:3 =

7.3 + (6 + 2.(2+3.2) – 7.√1) + 9:3 =

7.3 + (6 + 2. (2 + 6) – 7.√1) + 9:3 =

7.3 + (6 + 2. (8) – 7.√1) + 9:3 =

7.3 + (6 + 16 – 7.√1) + 9:3 =

7.3 + (6 + 16 – 7.1) + 9:3 =

7.3 + (6 + 16 – 7) + 9:3 =

7.3 + 15 + 9:3 =

21 + 15 + 3 = 39 Resultado

 

 

b]14 [7 + 4.3 {(-2)².2-6}] + (2² + 6 – 5.3) + 3 – (5 – 2³:2) =

 

14 [7 + 4.3 {4.2 – 6}] + (4 + 6 – 5.3) + 3 – (5 – 8:2) =

14 [7 + 4.3 {8 – 6}] + (4 + 6 – 15) + 3 – (5 – 4) = El signo – afecta todo lo que está adentro del ( ) se cambian signos

14 [7 + 4.3 {8 – 6}] + (4 + 6 – 15) + 3 (–5 + 4)

14 [7 + 12 {2}] + ( – 5) + 3 (– 1) = El signo + NO afecta todo lo que está adentro del ( ) NO se cambian signos

14 [7 + 12 {2}]  – 5 + 3 (– 1) =

14 [7 + 24]  – 5 + 3 (– 1) =

14 [31]  – 5 + 3 (– 1) =

434 – 5 + 3 – 1 =

434 + 3 – 5 – 1 =

437 – 6 = 431

 

c] 5(5 + 3.2:6 – 4) . (4:2 – 3 + 6) : (7 – 8:2 – 2)²=

 

5(5 + 6:6 – 4) * (2 – 3 + 6) : (7 – 4 – 2)²=

5(5 + 1 – 4) * (2 – 3 + 6) : (7 – 4 – 2)²=

5(2) * (5) : (1)²=

10 * 5 : 1 =

50 : 1 = 50 Resultado
