Question

porfavor podrian darme la respuesta paso a paso

Answer 1

Respuesta:

$\frac{1}{x} + \frac{1}{y} = \frac{4}{x + y} \\ \frac{x + y}{xy} = \frac{4}{x + y} \\ (x + y)^{2} = 4xy \\ {x}^{2} + 2xy + {y}^{2} = 4xy \\ {x}^{2} + 2xy - 4xy + {y}^{ 2} = 0 \\ {x}^{2} - 2xy + {y}^{2} = 0 \\ (x - y)^{2} = 0 \\ x = y$

$\sqrt{ \frac{x}{ {x}^{3} } } - \frac{2}{x + x} \\ \sqrt{ (\frac{1}{x} )^{2} } - \frac{2}{2x} \\ \frac{1}{x} - \frac{1}{x} = 0$
