Answer 2

O valor obtido na expressão numérica é :

${{\boxed{{\boxed{\Large{\boxed{\rm { -32 \: }}}}}}}}$

Montando a expressão :

$7\times(-2)^{2} -5\times(-2)^{3} -10^{2} \\\\\\7\times4-5(-2)^{3} -10^{2} \\\\\\28-5(-2)^{3}-10^{2} \\\\\\28-5(-8)-10^{2} \\\\\\28-(-40)-10^{2} \\\\\\28+40-10^{2} \\\\\\68-10^{2} \\\\\\68-100\\\\\\-32$

${{\boxed{{\boxed{\blue{\boxed{\Large{\rm { ATT: Miguel \: }}}}}}}}}$
