Answer 1

Answer:

So Option ( C ) 1 is the correct option

Step-by-step explanation:

We Have :-

i . ( j x k ) + j ( i x k ) + k ( i x j )

To Find :-

Value of i . ( j x k ) + j ( i x k ) + k ( i x j )

Solution :-

i x j = k

j x k = i

k x i = j

j x i = - k

k x j = - i

i x k = - j

i . i = 1

j . j = 1

k . k = 1

Acc to the question

i . ( i ) + j ( - j ) + k ( k )

i . i + j . - j + k . k

1 - 1 + 1

1

So Option ( C ) 1 is the correct option
