Answer 1

Explicação passo-a-passo:

$16.(-{1\over2})^3-(-18).\sqrt{{1\over36}}\\ \\ 16.(-{1\over8})-(-18).{1\over6}=\\ \\ -{16\over8}+{18\over6}=\\ \\ -2+3=+1\\ \\ ({1\over2}+{1\over3}).(-5)^{-1}+\sqrt{0.01} =\\ \\ ({3+2\over6}).(-{1\over5})+\sqrt{{1\over100}} =\\ \\ ({\not5\over6}).(-{1\over\not5})+{1\over10}=\\ \\ -{1\over6}+{1\over10}=\\ \\ mmc(6,10)=30\\ \\ {-5+3\over30}=-{2\over30}=-{1\over15}$
