Question

pls ans my this question and get marked as branliest !!!​

Answer 1

Step-by-step explanation:

$Given:\sqrt{x^{-1}y} \sqrt{y^{-1} z}\sqrt{z^{-1}x }$

$=\sqrt{\frac{1}{x}*y} \sqrt{\frac{1}{y}*z}\sqrt{\frac{1}{z} * x}$

$=\sqrt{\frac{y}{x}} * \sqrt{\frac{z}{y}} * \sqrt{\frac{x}{z}}$

$=\sqrt{\frac{y}{x} * \frac{z}{y} * \frac{x}{z}}$

$=\sqrt{1}$

$=1$

Hope it helps!
