Resposta:
[tex]-905270[/tex]
Explicação passo a passo:
[tex]\frac{2+2\times \:9907-618^2}{\frac{2}{5}}[/tex]
[tex]=\frac{\left(2+2\times \:9907-618^2\right)\times \:5}{2}[/tex]
[tex]=\frac{\left(19816-618^2\right)\times \:5}{2}[/tex]
[tex]=\frac{5\left(19816-618^2\right)}{2}[/tex]
[tex]=\frac{-1810540}{2}[/tex]
[tex]=-\frac{1810540}{2}[/tex]
[tex]=-905270[/tex]
