Question

urgente!!! por favor​

Answer 1

Resposta:

$a)\frac{-5+\sqrt{16} }{2.3}=\frac{-5+4}{6} =\frac{-1}{6}$

$b)\frac{-(-2)-\sqrt{9} }{2.(-2)}=\frac{+2-3}{-4}=\frac{-1}{-4}=\frac{1}{4}$

c) $\frac{-10+\sqrt{25} }{2.4}=\frac{-10+5}{8}=\frac{-5}{8}$

$d)\frac{-(-7)-\sqrt{64} }{2.(-3)}=\frac{+7-8}{-6} =\frac{-1}{-6} =\frac{1}{6}$

bons estudos!
