Question

Verify that a + b = b + a for each of the following. (b) * a = - 2/9, b = - 4/3​

Answer 1

Answer:

• After verifying we got -14/9 at both sides.

Verification..

a + b = b + a

we have,

• a = -2/9
• b = -4/3

Now put the numbers

$\: \: \sf \: - \frac{2}{9} + ( - \frac{4}{3} ) = - \frac{4}{3} + ( - \frac{2}{9} ) \\ \\ \: \: \sf \: - \frac{2}{9} - \frac{4}{3} = - \frac{4}{3} - \frac{2}{9} \\ \\ \: \: \sf \: - \frac{14}{9} = - \frac{14}{9}$

Hence, Verified

Answer 2

Answer:

L. H. S a+b = -2/9 + (-4/3)

= -2/9 - 4/3

= (-2-12) /9

= -14/9

R. H. S b+a = -4/3 + (-2/9)

= -4/3 - 2/9

= (-12-2) /9

= -14/9
