Question: \(i \times (j \times k) + j \times (k \times i) + k \times (i \times j)\) equals...

i×(j×k)+j×(k×i)+k×(i×j)i \times (j \times k) + j \times (k \times i) + k \times (i \times j) equals

A

i

B

j

C

k

D

0

Answer

0

Explanation

Solution

(i×i)+(j×j)+(k×k)=0.\mathbf{(i}\mathbf{\times}\mathbf{i) + (j}\mathbf{\times}\mathbf{j) + (k}\mathbf{\times}\mathbf{k) = 0.}
