6. Разделите одночлен на одночлен: a) $$\frac{10b^4}{5b^3} =$$ в) $$\frac{36y^7z^4}{(3y^2z)^2} =$$ б) $$\frac{98x^2yz^5}{14xyz^3} =$$ г) $$\frac{(-2p^3q^4)^3}{4p^8q^{10}} = $$

a) $$\frac{10b^4}{5b^3} = 2b^{4-3} = \textbf{2b}$$

в) $$\frac{36y^7z^4}{(3y^2z)^2} = \frac{36y^7z^4}{9y^4z^2} = 4y^{7-4}z^{4-2} = \textbf{4y^3z^2}$$

б) $$\frac{98x^2yz^5}{14xyz^3} = 7x^{2-1}y^{1-1}z^{5-3} = \textbf{7xz^2}$$

г) $$\frac{(-2p^3q^4)^3}{4p^8q^{10}} = \frac{-8p^9q^{12}}{4p^8q^{10}} = -2p^{9-8}q^{12-10} = \textbf{-2pq^2}$$
