Answer 1

$(-5xy^3)^2*(2xy^5z)^2=25x^2y^6*4x^2y^{10}z^2=100x^4y^{16}z^2 \ \ \ 1000*(-(0.1a^4b^5)^3)^2=1000*{(0.1a^4b^5)}^6=10^3*0.1^6a^{24}b^{30}= \\ =10^3*10^{-6}a^{24}b^{30}= frac{1}{10^3} a^{24}b^{30}= frac{a^{24}b^{30}}{1000} \ \ \ ((- frac{1}{3}a^3y)^2*3ab)^3 =( frac{1}{9}a^6y^2*3ab)^3 =( frac{1}{3}a^7by^2)^3 = frac{1}{27}a^{21}b^3y^6$
