Question

Verify the property: x × y = y × x by taking:

\[x = - \frac{1}{3}, y = \frac{2}{7}\]

Answer 1

\[\text{We have to verify that} x \times y = y \times x . \]
\[x = \frac{- 1}{3}, y = \frac{2}{7}\]
\[x \times y = \frac{- 1}{3} \times \frac{2}{7} = \frac{- 2}{21}\]
\[y \times x = \frac{2}{7} \times \frac{- 1}{3} = \frac{- 2}{21}\]
\[ \therefore \frac{- 1}{3} \times \frac{2}{7} = \frac{2}{7} \times \frac{- 1}{3}\]
\[\text{Hence verified .} \]
