Question

x=2/3,y=-5/6,z=5/9
x+(y+z)=(x+y)+z​

Answer 1

Step-by-step explanation:

LHS. RHS

= x+(y+z). =(x+y)+z

= ⅔+(5/6+ 5/9). =(⅔+5/6)+5/9

LCM=18. LCM=6

=⅔+(15+10/18). =(6+5/6)+5/9

=⅔+25/18. =11/6+5/9

LCM=18. LCM=18

=12+25/18. =33+10/18

=37/18. =43/18

LHS≠RHS

Therefore, X+(y+z)≠(x+y)+z
