a) $$\frac{10b^4}{5b^3} = \frac{10}{5} \cdot \frac{b^4}{b^3} = 2b$$ б) $$\frac{98x^2y^5z^3}{14xyz^3} = \frac{98}{14} \cdot \frac{x^2}{x} \cdot \frac{y^5}{y} \cdot \frac{z^3}{z^3} = 7xy^4$$ в) $$\frac{36y^7z^4}{(3y^2z)^2} = \frac{36y^7z^4}{3^2(y^2)^2z^2} = \frac{36y^7z^4}{9y^4z^2} = \frac{36}{9} \cdot \frac{y^7}{y^4} \cdot \frac{z^4}{z^2} = 4y^3z^2$$ г) $$\frac{(-2p^3q^4)^3}{4p^8q^{10}} = \frac{(-2)^3(p^3)^3(q^4)^3}{4p^8q^{10}} = \frac{-8p^9q^{12}}{4p^8q^{10}} = \frac{-8}{4} \cdot \frac{p^9}{p^8} \cdot \frac{q^{12}}{q^{10}} = -2pq^2$$
