(a×b)×c=(axc)xb=155x6=930
a×(b×c)=
(axc)xb=155x6=930
(axc)xb =155x6=93
c×(a×b)=(cxa)xb=155x6=930
b×(c×a)
=6x155=930

toate dau lafel deoarece inmultirea este comutativa

(a×b)×c=(axc)xb=155x6=930
ax(bxc)=(axc)xb=155x6=930
cx(axb)=(axc)xb=155x6=930
bx(cxa)=(axc)xb=155x6=930
poate te miri sa vezi raspunsurile dar am folosit asociativitatea
