___ ___ 3
z = \/ 5 *\/ x - -----
___
\/ y
$$z = \sqrt{5} \sqrt{x} - \frac{3}{\sqrt{y}}$$
Solución detallada
Tenemos la ecuación:
$$z = \sqrt{5} \sqrt{x} - \frac{3}{\sqrt{y}}$$
cambiamos:
$$z = \sqrt{5} \sqrt{x} - \frac{3}{\sqrt{y}}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
Obtenemos la respuesta: z = -3/sqrt(y) + sqrt(5)*sqrt(x)
$$z = \sqrt{5} \sqrt{x} - \frac{3}{\sqrt{y}}$$
cambiamos:
$$z = \sqrt{5} \sqrt{x} - \frac{3}{\sqrt{y}}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
z = -3/sqrty + sqrt5sqrtx
Obtenemos la respuesta: z = -3/sqrt(y) + sqrt(5)*sqrt(x)
