Question

|x *y| =|×| *|y| where x=7/-9 y= - 13/27,then verify​

Answer 1

Solution,

L.H.S = |x*y|

         = $|\frac{-7}{9}*\frac{-13}{27}|$

         =$|\frac{91}{243}|$

         =$\frac{91}{243}$

R.H.S = |x|*|y|

         =$|\frac{-7}{9} |*|\frac{13}{27} |$

         = $\frac{7}{9} *\frac{13}{27}$

         = $\frac{91}{243}$

As L.H.S = R.H.S, so it is verified that |x *y| =|×| *|y| when x=7/-9 y= - 13/27.​
