Question

1. Qual será o resultado dessa expressão?

[2 . (10 - 4² : 2) + 6²] : (2³ - 2²)​

Answer 1

Resposta:

$\sf [ 2 \cdot ( 10 - 4 ^ { 2 } : 2 ) + 6 ^ { 2 } ] : ( 2 ^ { 3 } - 2 ^ { 2 } )$

$\sf \dfrac{2\left(10-\frac{16}{2}\right)+6^{2}}{2^{3}-2^{2}}\approx 10$

$\sf \dfrac{2\left(10-8\right)+6^{2}}{2^{3}-2^{2}}\approx 10$

$\sf \dfrac{2\times 2+6^{2}}{2^{3}-2^{2}}\approx 10$

$\sf \dfrac{4+6^{2}}{2^{3}-2^{2}}\approx 10$

$\sf \dfrac{4+36}{2^{3}-2^{2}}\approx 10$

$\sf \dfrac{40}{2^{3}-2^{2}}\approx 10$

$\sf \dfrac{40}{8-2^{2}}\approx 10$

$\sf \dfrac{40}{8-4}=10$
