Question

Resolva as expressão abaixo d) 5²+2+4.10-12 e) [4²+(5-3)³ ]:(9-7) ³

Answer 1

D)

$\large\sf{} {5}^{2} + 2 + 4 \times 10 - 12 \\ \large\sf{}25 + 2 + 4 \times 10 - 12 \\ \large\sf{}25 + 2 + 40 - 12 \\ \large\sf{}67 - 12 \\ {\large\boxed{\boxed{  { \large \sf 55}}}}$

E)

$\large\sf{} \{ {4}^{2} + \left(5 - 3\right)^{3} \} \div\left(9 - 7\right)^{3} \\ \\ \large\sf{} \{ {2}^{4} + \left(5 - 3\right)^{3} \} \div \left(9 - 7\right)^{3} \\ \\ \large\sf{} \left( {2}^{4} + {2}^{3} \right) \div \left(9 - 7\right)^{3} \\ \large\sf{}\left( {2}^{4} + {2}^{3} \right) \div {2}^{3} \\ \large\sf{}\left(16 + {2}^{3} \right) \div {2}^{3} \\ \large\sf{}\left(16 + 8\right) \div {2}^{3} \\ \large\sf{}24 \div {2}^{3} \\ \\ \large\sf{} \dfrac{24}{ {2}^{3} } \\ \\ \large\sf{} \dfrac{24}{8} \\ \\ \large\sf{} \frac{24 \div 8}{8 \div 8} \\ \\ {\large\boxed{\boxed{  { \large \sf 8}}}}$

${\large\boxed{\boxed{  { \large \sf Bons~Estudos }}}}$
