Question

-5
b) If a, b, c are three rational numbers where
= 3,6 = 9 and c =
6
Verify: a + (b + c) = (a + b) + C​

Answer 1

Answer:

L.H.S

a + (b + c) = 3 + (6 + 9)

= 3+ 15

a + (b + c) = 18. ..............(1)

R.H.S

(a + b) + C = (3 + 6) + 9

= 9 + 9

(a + b) + C = 18. ..............(2)

From (1) & (2)

a + (b + c) = (a + b) + C

Hence verified
