$$\frac{(x^3)^2}{x^2 \cdot x^3} = \frac{x^{3 \cdot 2}}{x^{2+3}} = \frac{x^6}{x^5} = x^{6-5} = x^1 = x$$
Ответ: x
$$\frac{(x^4)^2 \cdot x^3}{x^5 \cdot (x^3)^2} = \frac{x^{4 \cdot 2} \cdot x^3}{x^5 \cdot x^{3 \cdot 2}} = \frac{x^8 \cdot x^3}{x^5 \cdot x^6} = \frac{x^{8+3}}{x^{5+6}} = \frac{x^{11}}{x^{11}} = x^{11-11} = x^0 = 1$$
Ответ: 1
$$\frac{(x^3)^3}{x^2 \cdot x^4} = \frac{x^{3 \cdot 3}}{x^{2+4}} = \frac{x^9}{x^6} = x^{9-6} = x^3$$
Ответ: x3
$$\frac{(x^3)^5}{(x^2)^4 \cdot x^3} = \frac{x^{3 \cdot 5}}{x^{2 \cdot 4} \cdot x^3} = \frac{x^{15}}{x^8 \cdot x^3} = \frac{x^{15}}{x^{8+3}} = \frac{x^{15}}{x^{11}} = x^{15-11} = x^4$$
