Question

1) calcule as expreçoes numéricas a seguir... me ajudem pfv
​

Answer 1

$7-(1^{2} +\sqrt{9} ) = {\boxed{\sf \ \red{3}}}\\\\-9-(\sqrt{25} -1+3^{2}) = {\boxed{\sf \ \red{-22}}}\\\\10-(3x4+5)+2^{2} = {\boxed{\sf \ \red{-3x^{4}+9 }}} \\\\(13-\sqrt{49})+2^{3} -1= {\boxed{\sf \ \red{13}}} \\\\-(\sqrt{10} (-4)-(9-8)+3= {\boxed{\sf \ \red{14.64911064}}}\\\\-50-[37-(15-8)]= {\boxed{\sf \ \red{-80}}}$
