Question

if a= -5/9,b=5/6 c=-5/18 verify (a+b)+c=a+(b+c)​

Answer 1

Solution:

Given :

• a = -5/9
• b = 5/6
• c = -5/18

T0 verify: (a+b)+c=a+(b+c)

LHS term :

(a+b)+c

☞ ( -5/9 + 5/6 ) -5/18

☞ -10+15/18 - 5/18

☞ 5/18 - 5/18

☞ 0

RHS Term :

a+(b+c)

☞ -5/9 + (5/6 -5/18 )

☞ -10+15/18 - 5/18

☞ 5/18 - 5/18

☞ 0

Hence , It's Proved!

Answer 2

Answer:

If a = -8 , b = -7 and c= 6 verify that (a + b) + c = a + ( b + c )
