Question

if a equal minus 8 B equal minus 70 equal 6 verify that (a + b )+ c = a + (b + c)

Answer 1

Hi...☺

Here is your answer...✌

GIVEN THAT,

a = -8 , b = -70 , c = 6

We need to verify

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

LHS

= (a + b)+c

= [-8 + (-70)] + 6

= (-8-70)+6

= -78+6

= -72

Now,

RHS

= a + (b+c)

= -8 + (-70+6)

= -8+(-64)

= -8-64

= -72

•°• LHS = RHS [VERIFIED]
