b)5(-2)+10=-10+10=0 (admite)
c)-8(-2)-16=16-16=0 (admite)
d) -2 x -2 + 4 = 4 + 4 = 8 (nu admite)
e)8(-2)-4=-16-4=-20 (nu admite)
f)|-6|(-2)+12=6(-2)+12=-12+12=0(admite)
g)($( \sqrt{2} -1)(-2)-3-2 \sqrt{2}=$=-2$\sqrt{2}$+2-3-2$\sqrt{2}$=$-4 \sqrt{2} -1$ (nu admite)
h)$\sqrt{3(-2)} + \sqrt{12} = \sqrt{-12} + \sqrt{12}$ (nu admite)
