Question

If a= -8 , b= -7 , c = -5 verify that (a+b)+c= a+(b+c) mention the property

Answer 1

if we open the brackets the equation will become a+b+c on L.H.S as well as R.H.S

therefore the eq will be -20=-20

Answer 2

verify that (a+b)+c=a+(b+c)

A= -8 ,b= -7 ,c= -5

Answer:-

From the question ,

A=8 , b= -7 and c = -5

To verify (a+b)=a+b

let us take left hand side (LHS)

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

= (-8)-7 (-5)

= -8 -7 -5

= -20

now,

let us take right hand side (RHS)

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

= -8 -7 -5

= -20

By comparing LHS and RHS

LHS = RHS

- 20 = - 20

Hence, the value of A ,B and C is verified.
