Question

please answer my question ​

Answer 1

$x = 2 \\ y = \frac{ - 1}{2} \\ z = \frac{1}{3} \\ \\ \\ \\ x \times (y \times z) \\ = 2 \times ( \frac{ - 1}{2} \times \frac{1}{3} ) \\ = 2 \times \frac{ - 1}{6} \\ = \frac{ - 1}{3} \\ \\ \\ (x \times y) \times z \\ = (2 \times \frac{ - 1}{2} ) \times \frac{1}{3} \\ = - 1 \times \frac{1}{3} \\ = \frac{ - 1}{3}$
