Question

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

\[x = 2, y = \frac{7}{- 8}\]

Answer 1

\[\text{We have to verify that} x \times y = y \times x . \]
\[ x = 2, y = \frac{7}{- 8}\]
\[ x \times y = 2 \times \frac{7}{- 8} = \frac{7}{- 4}\]
\[y \times x = \frac{7}{- 8} \times 2 = \frac{7}{- 4}\]
\[ \therefore 2 \times \frac{7}{- 8} = \frac{7}{- 8} \times 2\]
\[\text{Hence verified .} \]
