Question

3{-1+12×[-13+4×(1-1/3)-1]-1}

Answer 1

Resposta:

-414

Explicação passo-a-passo:

3{-1 + 12 × [-13 + 4 × (1 - ⅓) - 1] - 1}

3{-1 + 12 × [-13 + 4 × (3/3 - 1/3) - 1] - 1}

3{-1 + 12 × [-13 + 4 × (⅔) - 1] - 1}

3{-1 + 12 × [-13 + 8/3 - 1] - 1}

3{-1 + 12 × [(-39 + 8 - 3)/3] - 1}

3{-1 + 12 × [-34/3] - 1}

3{-1 - 4 × 34 - 1}

3{-2 - 136}

3{-138}

-414

Answer 2

Olá, bom dia!

Resposta:

$\Large{\color{blue}{\boxed{\boxed{\boxed{\mathsf{\color{green}{-414}}}}}}}$

Explicação passo-a-passo:

$\mathsf{3 \left\{-1+12 \cdot \left[-13+4 \cdot \left(1- \dfrac{1}{3} \right)-1 \right]-1 \right\}}$

$\mathsf{3 \left\{-1+12\cdot \left[-13 +4 \cdot \left(\dfrac{2}{3} \right) -1 \right]-1 \right\}}$

$\mathsf{3 \left\{-1 +12\cdot \left[-13 +4 \cdot \dfrac{2}{3} -1 \right]-1 \right\}}$

$\mathsf{3 \left\{-1+12 \cdot \left[-13 +\dfrac{8}{3}-1 \right]-1 \right\}}$

$\mathsf{3 \left\{-1+12\cdot \dfrac{-13 \cdot (3)+8-1\cdot (3)}{3}-1 \right\}}$

$\mathsf{3 \left\{-1+12\cdot \left(-\dfrac{34}{3}\right)-1 \right\}}$

$\mathsf{3 \left\{-1+ \cancel{12} \cdot \left(-\dfrac{34}{\cancel{3}}\right)-1 \right\}}$

$\mathsf{3 \left\{-1+4 \cdot (-34) -1\right\}}$

$\mathsf{3 \left\{-1-136-1\right\}}$

$\mathsf{3 \left\{-138\right\}}$

$\boxed{\mathsf{\color{green}{-414}}}$
