Question
Verify the property: $x \times y = y \times x$ by taking: $\text{x}=0,\text{y=}\frac{-15}{8}$
✓

Answer

$\text{x}\times\text{y}=\text{y}\times\text{x}$
$\text{x}=0,\text{y=}\frac{-15}{8}$
$\text{L.H.S.}=\text{x}\times\text{y}=0\times\frac{-15}{8}=0$
$\text{R.H.S.}=\text{y}\times\text{x}=\frac{-15}{8}\times0=0$
$\therefore\text{L.H.S.}=\text{R.H.S.}$
