Question

{ -[5 + (3 × 7 - 4) ]} + 3^2 × 2 -(8^2 - 60) × 5​

Answer 1

Resposta:

$- 24$

Explicação passo-a-passo:

$( - (5 + (3 \times 7 - 4))) + {3}^{2} \times 2 - ( {8}^{2} - 60) \times 5$

$- (5 + (21 - 4)) + {3}^{2} \times 2 - ( {8}^{2} - 60) \times 5$

$- (5 + (21 - 4)) + 9 \times 2 - ( {8}^{2} - 60) \times 5$

$- (5 + (21 - 4)) + 9 \times 2 - (64 - 60) \times 5$

$- (5 + 17) + 9 \times 2 - (64 - 60) \times 5$

$- (5 + 17) + 18 - (64 - 60) \times 5$

$- (5 + 17) + 18 - 4 \times 5$

$- 22 + 18 - 4 \times 5$

$- 22 + 18 - 20$

$- 24$
