Question

verify the property x*y=y*x by taking: 1)x=-1/3,y=2/7 2)x=-3/5,y=-11/13 3)x=2,y=7/-8

Answer 1

Answer:

$x \times y = y \times x \\ l.h.s. = x \times y \\ = \frac{ - 1}{3} \times \frac{2}{7} \\ = \frac{ - 2}{21} \\ r.h.s. = y \times x \\ = \frac{2}{7} \times \frac{ - 1}{3} \\ = \frac{ - 2}{21} \\ l.h.s = r.h.s. \\ x \times y = y \times x \: s \: proved$
