Question

50-3×{7+8:4-[20-3×(9-5)]} conta e resposta ​

Answer 1

Explicação passo-a-passo:

50 - 3 × {7+8 : 4 - [ 20 - 3 × (9 - 5)]}

= 50 − 3( 7 + 2 − (20 − 3(9 − 5)))

= 50 − 3( 9 − ( 20 − 3( 9 − 5 )))

= 50 − 3( 9 − ( 20 − (3)(4)))

= 50 − 3( 9 − (20 − 12))

= 50 − 3(9 − 8)

= 50 − (3)(1)

= 50 − 3

= 47
