Question

me ajudem nessa tbm,por favor​

Answer 1

$a) \frac{x}{ \sqrt{x} } = \frac{x \sqrt{x} }{x} = \sqrt{x} \\ \\ b) \frac{{x} }{2 \sqrt{y} } = \frac{x \sqrt{y} }{2y} \\ \\ c) \frac{xy}{5 \sqrt{x} } = \frac{xy \sqrt{x} }{5x} = \frac{y \sqrt{x} }{5} \\ \\ d) \frac{x \sqrt{y} }{y \sqrt{x} } = \frac{x \sqrt{y } \sqrt{x} }{yx} = \frac{ \sqrt{y} \sqrt{x} }{y}$
