Question

If a =-8 , b=-7, c=6 verfi that (a+b)+c= a+(b+c) solution

Answer 1

Step-by-step explanation:

a = -8 , b = -7 , c = 6

R.T.P : (a+b) + c = a + (b+c)

⇒ (-8-7) + 6 = -8 + (-7+6)

⇒ -15 + 6 = -8 - 1

⇒ -9 = -9

Hence verified.

Answer 2

Answer:

LHS={-8+(-7)}+6

= -15+6

= -9

RHS= -8+(-7+6)

= -8-1

= -9

therefore,

LHS=RHS
