Question

यदि a = -5, b = -7, c = 6, तो सत्यापित कीजिए (a + b) + c= a+(b+c)​

Answer 1

Step-by-step explanation:

put the values

[(-5)+(-7)]+6 = -5+[(-7)+6]

(-12)+6 = -5+-1

-6 = -6

hope it will help you...

Answer 2

Answer:

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

(-5+-7)+6 = -5+(-7+6)

L.H.S=  (-5+-7)+6

        = (-5-7)+6

        = (-12)+6

         =-6

R.H.S= -5+(-7+6)

        = -5+(-1)

         = -5-1

         =-6

∴ L.H.S = R.H.S

Hence, verified

Hope it helps!!!
