Question
Verify the property x × y = y × x of rational numbers by using
`x = (-5)/7` and `y = 14/15`
Advertisements
Solution
Given, `x = (-5)/7` and `y = 14/15`
Then, LHS = x × y
= `(-5)/7 xx 14/15`
= `(-70)/105`
= `(-2)/3`
RHS = y × x
= `14/15 xx (-5)/7`
= `(-70)/105`
= `(-2)/3`
∴ LHS = RHS
Hence, xy = yx
