Решение задания 6

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

б) $$\frac{98x^2y^5z^3}{14xyz^3} = 7x^{2-1}y^{5-1}z^{3-3} = 7xy^4z^0 = $$\\mathbf{7xy^4}$$

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

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