VAMOS A SUA PERGUNTA:⇒⇒

$[ ( 64 : 8 - 19 : 19 ) ^ { 2 } + 50 : 25 ] - ( 3 \times 5 - 7 \times 2 )$

$\left(\dfrac{64}{8}-1\right)^{2}+\dfrac{50}{25}-\left(3\times 5-7\times 2\right)\approx 50$

$\left(8-1\right)^{2}+\dfrac{50}{25}-\left(3\times 5-7\times 2\right)\approx 50$

$7^{2}+\dfrac{50}{25}-\left(3\times 5-7\times 2\right)\approx 50$

$49+\dfrac{50}{25}-\left(3\times 5-7\times 2\right)=50$

$49+2-\left(3\times 5-7\times 2\right)=50$

$51-\left(3\times 5-7\times 2\right)=50$

$51-\left(15-7\times 2\right)=50$

$51-\left(15-14\right)=50$

$51-1=50$
