Question

verify a+{b+c}={a+b}+c for a=1/2 b=3/5 c=-3/2
​

Answer 1

1/2+(3/5-3/2)=(1/2+3/5)-3/2

1/2+(6-15/10)=(11/10)-3/2

1/2-9/10=11/10-3/2

5-9/10=11-15/10

-4/10=-4/10

Hence L.H.S=R.H.S....hence verified

Answer 2

Ans:

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

1/2+(3/5-3/2) = (1/2+3/5)-3/2

1/2+(-9/10) = (11/10)-3/2

-4/10 -4/10
