on G=Z^3, we define an operation (k1,k2,k3)(l1,l2,l3) = (k1+ (- 1)^k3.l1, k2 l2, k3 l3). Prove that G is a group

Step-by-step explanation:

A{6d+4.5e45d+4.5e=16.5=4

{6d+4.5e45d+4.5e=16.5=4

D{6d+4.5e6d+0.6e=16.5=4.8

{6d+4.5e6d+0.6e=16.5=4.8

B{30d+22.5e5d+0.5e=82.5=4

{30d+22.5e5d+0.5e=82.5=4

E{12d+9e10d+0.5e=33=8

{12d+9e10d+0.5e=33=8

C

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
