Question

resolva a expressão ​

Answer 1

$\mathbf {3 \times 4^3 - [5 \times 6^0 + 7 \times (9^2 - 80)]}$

$\mathbf {3 \times 64 - [5 \times 1 + 7 \times (81 - 80)]}$

$\mathbf {3 \times 64 - [5 \times 1 + 7 \times 1]}$

$\mathbf {3 \times 64 - [5 + 7]}$

$\mathbf {3 \times 64 - 12}$

$\mathbf {192 - 12}$

$\red{\mathbf{\boxed{\boxed{180}}}}$
