Question

1. Verify property (a - b) = (b -a):
(a) 42,56
(b) 19, 17
(e) 453, 762
(f) 143, 918​

Answer 1

52. is answer. ,,,,,,,,,,,,

Answer 2

Step-by-step explanation:

Given that:-

a)Given numbers are 42,56

Let a=42 and b=56

now

LHS=(a-b)=42-56=-14

RHS=(b-a)=56-42=14

LHS≠RHS

(a-b)≠(b-a)

b)Given numbers are 19,17

Let a=19, b=17

LHS:-(a-b)=19-17=2

RHS:-(b-a)=17-19=-2

LHS≠RHS

(a-b)≠(b-a)

c)Given numbers are 453,762

Let a=453 and b=762

LHS:-(a-b)=453-762=-309

RHS:(b-a)=762-453=309

LHS≠RHS

(a-b)≠(b-a)

d)Given numbers are 143 ,918

Let a=143,b=918

LHS:(a-b)=143-918=-775

RHS:(b-a)=918-143=775

LHS≠RHS

(a-b)≠(b-a)

From all above we conclude that

(a-b)≠(b-a)

Commutative property under subtraction does not hold in the set of integers
