Question

7. For rational numbers x and y, verify the property x×y=y×x by taking
(I) x=-3/5, y=10/7​

Answer 1

$\huge\red{A}\pink{N}\orange{S}\green{W}\blue{E} \gray{R}$

By using the property

x × y = y × x

-3/5 × -11/13 = -11/13 × -3/5

(-3×-11)/(5×13) = (-11×-3)/(13×5)

33/65 = 33/65

Hence, the property is satisfied.

Answer 2

Step-by-step explanation:

x=-3/5, y=10/7

L.H.S= x×y

= -3/5×10/7 (putting the values of x and y)

=-6/7

R.HS.= y×x

=10/7×(-3/5)

=-6/7

=> -6/7=-6/7

=>L.H.S= R.H.S

hence verified
