Question

verify x+( y+ z) =(x+y) + z value of the x = 2/3, y =_ 5/6, z = - 7/9

Answer 1

$hey \: mate,\\ = \frac{2}{3} + ( \frac{5}{6} + \frac{7}{9} ) = \frac{41}{18 } \\ = ( \frac{2}{3} + \frac{5}{6}) + \frac{7}{9} = \frac{41}{18} \\ i \: hope \: this \: helps \: you \:$

Answer 2

i do not under stand y=_5/6 so i take it y=-5/6 L.H.S. X+(y+z)=2/3+{-5/6+(-7/9)}=2/3+(-15-14/18)=2/3+(-29/18)=2/3-29/18=12-29/18= -17/18 R.H.S.(x+y)+z={2/3+(-5/6)}+(-7/9)=(2/3-5/6)-7/9=(4-5/6) - 7/9=--1/6-7/9= -3-14/18= -17/18 L.H.S=R.H.P.(PROVED) PLEASE MARK THE ANSWER BRAINLIST.
