Question

verify that (x+y)+z=x+(y+z) if x=-2/5 y=6/11 z=-3/2​

Answer 1

Answer:

$<font color = orange>$

( -2/5 + 6/11 ) + (-3/2) = ( -2/5 ) + [ 6/11 + ( -3/2 ) ]

( -22 + 30 / 55 ) + ( -3/2 ) = ( -2/5 ) + [ 12 - 33/22 ]

8/55 - 3/2 = -2/5 + ( - 21/22 )

8/55 - 3/2 = -2/5 - 21/22

16 - 165/110 = -44 - 105/110

-149/110 = -149/110
