AXB=?
(AXB)XC=?
BXC=?
AX(BXC)

Answer 1

Axb=2,33x4,1=9,553
5,5x8,4=46,2
0,2x0,41=0,082
21,2x44,5=943,4
(axb)xc= 9,553x7,2=68,7816
46,2x3,25=150,15
0,082x3,2=0,2624
943,4x5,24=4943,416

Ax(bxc) =2,33x(4,1x7,2)=2,33x29,52=68,7816
5,5x(8,4x3,25)=5,5x27, 3=150,15
0,2x(0,41x3,2)=0,2x1,312=0,2624
21,2x(44,5x5,24)=21,2x233, 18=4943,416
