Question

determine o valor das expressoes a seguir
a) $\frac{0,5 . 10^{3} - 2^{-1} . \sqrt[3]{1000} }{(1,3111)^{-1} }$

Answer 1

Resposta:

$\boxed{\mathtt{648,9945}}$

Explicação passo-a-passo:

$\\ \displaystyle \mathsf{\frac{0,5 \cdot 10^3 - 2^{- 1} \cdot \sqrt[3]{1000}}{(1,3111)^{- 1}} =} \\\\\\ \mathsf{\frac{500 - \left ( \frac{1}{2} \right )^1 \cdot \sqrt[3]{10^3}}{\left ( \frac{1}{1,3111} \right )^1} =} \\\\\\ \mathsf{\frac{500 - \frac{10}{2}}{\frac{1}{\frac{13111}{10000}}}}$

$\\ \displaystyle \mathsf{\frac{500 - 5}{\frac{10000}{13111}} =} \\\\\\ \mathsf{495 \cdot \frac{13111}{10000} =} \\\\\\ \boxed{\boxed{\mathsf{\frac{6489945}{10000}}}}$
