Question

5. Take a = -6, b = 9, c = 5 and verify that
(i) a + b = b + a
(ii) a - b + b - a
(iii) a + (b + c) = (a + b) + c (iv) a - (b-c) + (a - b)-C
(v) b+0=b​

Answer 1

Answer:

the answer will be

Step-by-step explanation:

a=-6

b=9

c=5

(I) =a+b=b+a

=-6+9=9-6

=3=3

lhs=rhs

(II) a-b+b-a

=-6-9+9+6

=-15+15=0

(III) a+(b+c)=(a+b)+c

=-6+(9+5)=(-6+9)+5

=-6+14=3+5

=8=8

lhs=rhs

(Iv)a-(b-c) +(a-b) -c

-6-(9-5)+(-6-9)-5

=-6-4+-15-5

-10-10=-20

(v) b+0=b

9+0=9
