помргите!!!!1!1!1!1!1!1!1!!​

Answer 1

Ответ:

Объяснение:

$\displaystyle\left(\frac{z}{4} +\frac{z}{3}\right)\cdot\frac{1}{z^2} =\frac{3z+4z}{12} \cdot\frac{1}{z^2} = \frac{7z}{12z^2} =\frac{7}{12z}$

Answer 2

$(\frac{z}{4}+\frac{z}{3})*\frac{1}{z^2}=\frac{7}{12}z*\frac{1}{z^2}=\frac{7}{12}*\frac{1}{z}=\frac{7}{12z}$
