Explicação passo a passo:
[tex]\mathsf{a)\:(\:5^{-1} \times 5^{-3} \times 5^{-2}\:) = (\:5^{-1-3-2}\:) = \boxed{\mathsf{5^{-6}}}}[/tex]
[tex]\mathsf{b)\:\dfrac{0,001 \times (0,001)^3}{1000 \times 0,00001} = \dfrac{10^{-3} \times 10^{-9}}{10^3 \times10^{-5}} = \dfrac{10^{-3-9}}{10^{3-5}} = \dfrac{10^{-12}}{10^{-2}} = 10^{-12+2} = \boxed{\mathsf{10^{-10}}}}[/tex]
