Answer 1

Ответ:

1) $\frac{a^3}{b^6} \frac{b^3}{a^2} = \frac{a^3b^3}{a^2b^6} = \frac{a}{b^3}$

2) $x^7y^2\frac{y^3z^2}{y^5z} = \frac{x^7y^2y^3z^2}{y^5z} = \frac{x^7y^5z^2}{y^5z} = x^7z$

3) $\frac{x^3}{y^7} \frac{y^6}{x} = \frac{x^3y^6}{xy^7} = \frac{x^{2} }{y}$

4) $\frac{t^7u^5}{t^4u^4} t^3u^3 = \frac{t^7u^5 t^3u^3}{t^4u^4} = \frac{t^{10}u^8}{t^4u^4}= t^{6}u^4$
