Ответ:

$4)\ \ (abc)^{10}=a^{10}b^{10}c^{10}\ \ \ ,\ \ \ \ (-4a)^3=-64a^3\ \ ,\ \ \ (-5xy)^2=25x^2y^2\ \ ,\\\\\\5)\ \ \ \Big(\dfrac{1}{10}xyz\Big)^9=\dfrac{1}{10^9}\, x^9y^9z^9\ \ ,\ \ \ -a^3=(-a)^3\ \ ,\ \ \ 49x^2y^2=(7xy)^2\ \ ,\\\\\\-32a^5c^5=(-2ac)^5\ \ ,\ \ \ -\dfrac{1}{8}\, a^3b^3c^3=\Big(-\dfrac{abc}{2}\Big)^3$

$6)\ \ 4^3\, 5^3=(4\cdot 5)^3=20^3=8000\ \ ,\\\\\\\Big(3\dfrac{1}{3}\Big)^4\cdot (1,5)^4=\Big(\dfrac{10}{3}\Big)^4\cdot \Big(\dfrac{3}{2}\Big)^4=\dfrac{10^4}{3^4}\cdot \dfrac{3^4}{2^4}=\dfrac{10^4}{2^4}=5^4=625\\\\\\7)\ \ \ (x^3)^3=x^9\ \ ,\ \ \ (-a^5)^2=a^{10}\ \ ,\ \ \ (-a^3)^{2n}=a^{6n}$
