Приведи дроби \(\frac{2y}{u^2 + 2uy}\), \(\frac{y}{ut - 7u^2}\) и \(\frac{t+14y}{ut+2yt-14uy-7u^2}\) к общему знаменателю.

Выбери правильный вариант (варианты) ответа:

• другой ответ
• \(\frac{2yt-14yu}{u(u+2y)(t-7u)}, \, \frac{yu+2y^2}{u(u+2y)(t-7u)} \,\text{и}\, \frac{ut+14uy}{u(u+2y)(t-7u)}\)
• \(\frac{2y}{u(u+2y)}, \frac{yu+2y^2}{u(u+2y)} \text{ и } \frac{ut+14uy}{u(u+2y)}\)
• \(\frac{2yt-14yu}{\left(u+2y\right)\left(t-7u\right)}, \,\frac{yu-2y^{2}}{\left(u+2y\right)\left(t-7u\right)}\,\text{и}\,\frac{ut-14uy}{\left(u+2y\right)\left(t-7u\right)}\)
• \(\frac{2yt-14yu}{(u+2y)(t-7u)}, \, \frac{yu+2y^2}{(u+2y)(t-7u)} \,\text{и}\, \frac{ut+14uy}{(u+2y)(t-7u)}\)
• \(\frac{2yt-7u}{u(u+2y)(t-7u)}, \frac{yu+2y}{u(u+2y)(t-7u)} \text{и} \frac{ut+14y}{u(u+2y)(t-7u)}\)
