Respuesta:
a) 18 + [ 13 + 4 – ( 5 – 7 ) + 6 ] = 43
18 + [ 13 + 4 – ( -2 ) + 6 ] = 43
18 + [ 13 + 4 +2 + 6 ] = 43
18 + 25= 43
23 = 23
b) 15 – [12 – 3 . 4 . (– 5 ) + 10] = – 67
15 – [12 – 3 . 4 . (– 5 ) + 10] = – 67
15 – [12 + 60 + 10] = – 67
15 – [82] = – 67
15 – 82 = – 67
- 67 = - 67
c) 18 – [2 – ( 4 + 5 ) . (– 4 + 9)] = 61
18 – [2 – ( 9 ) . (5)] = 61
18 – [2 – ( 45)] = 61
18 – [2 – 45] = 61
18 – [- 43] = 61
18 + 43 = 61
61 = 61
d ) – [13 – ( 12 – 6 )] – [ 3 . (– 6)] = 11
– [13 – ( 6 )] – [ 3 . (– 6)] = 11
– [13 – 6 ] – [ 3 . – 6] = 11
– [7 ] – [ - 18] = 11
– 7 + 18 = 11
11 = 11
e) ( 5 – 4 . 6 ) . [ 3 – (– 2 ) . 4 . (– 3 )] = 399
( 5 – 24 ) . [ 3 – (– 2 ) . 4 . (– 3 )] = 399
- 19 . [ 3 + 2 . 4 . – 3 ] = 399
- 19 . [ 3 - 24 ] = 399
- 19 . - 21 = 399
399 = 399
Respuesta:
Ahí esta la respuesta.
Explicación paso a paso:
a) 18 + [ 13 + 4 – ( 5 – 7 ) + 6 ] = 43
18 + [ 13 + 4 – (– 2) + 6 ] = 43
18 + [ 13 + 4 +2 + 6 ] = 43
18 + [ 25 ] = 43
18 + 25 = 43
43 = 43
b) 15 – [ 12 – 3 . 4 . (– 5 ) + 10 ] = – 67
15 – [ 12 – 3 . (– 20 ) + 10 ] = – 67
15 – [ 12 + 60 + 10 ] = – 67
15 – [ 82 ] = – 67
15 – 82 = – 67
– 67 = – 67
c) 18 – [ 2 – ( 4 + 5 ) . (– 4 + 9) ] = 61
18 – [ 2 – ( 9 ) . (5) ] = 61
18 – [ 2 – 45 ] = 61
18 – [ – 43 ] = 61
18 +43 = 61
61 = 61
d ) – [ 13 – ( 12 – 6 ) ] – [ 3 . (– 6) ] = 11
– [ 13 – ( 6 ) ] – [ 3 . (– 6) ] = 11
– [ 13 – 6 ] – [ 3. (– 6) ] = 11
– [ 7 ] – [ 3. (– 6) ] = 11
– 7 – [ – 18 ] = 11
– 7 + 18 = 11
11 = 11
e) ( 5 – 4 . 6 ) . [ 3 – (– 2 ) . 4 . (– 3 )] = 399
( 5 – 24 ) . [ 3 – (– 2 ) . (– 12 )] = 399
( – 19 ) . [ 3 – ( 24 ) ] = 399
( – 19 ) . [ – 21 ] = 399
399 = 399
Espero haberte ayudado: :))
