Question

X= -4/7 y= -3/8 z= 16/5 verify property (x×y) ×z = x× (y × z) in LHS and RHS From​

Answer 1

Step-by-step explanation:

$(x \times y)z = x (y \times z) \\( - \frac{4}{7} \times - \frac{3}{8} ) \times \frac{16}{5} = - \frac{4}{7} ( - \frac{3}{8} \times \frac{16}{5} ) \\ \frac{12}{56} \times \frac{16}{5} = - \frac{4}{7} \times - \frac{48}{40} \\ \frac{24}{35} = \frac{24}{35} \\ proved$
