Hope u like my process
=====================
$= > \: \sqrt{ {x}^{ - 1} y} \times \sqrt{ {y}^{ - 1} z} \times \sqrt{ {z}^{ - 1}x } \\ \\ = \sqrt{ {x}^{ - 1} \times y \times {y}^{ - 1} \times z \times {z}^{ - 1} \times x } \\ \\ = \sqrt{ {x}^{1 - 1} \times {y}^{1 - 1} \times {z}^{1 - 1} } \\ \\ = \sqrt{ {x}^{0} \times {y}^{0} \times {z}^{0} } = \sqrt{1 \times 1 \times 1} \\ \\ = \sqrt{1} = 1... < proved > ....$
Hope this is ur required answer
