Question
Verify the property: x × y = y × x by taking:
Solution
\[\text{We have to verify that} x \times y = y \times x . \]
\[ x = 0, y = \frac{- 15}{8}\]
\[ x \times y = 0 \times \frac{- 15}{8} = 0\]
\[y \times x = \frac{- 15}{8} \times 0 = 0\]
\[ \therefore 0 \times \frac{- 15}{8} = \frac{- 15}{8} \times 0\]
\[\text{Hence verified .}\]
