The value of v x and w is (24i ) +(64j ) - (10k)
Step-by-step explanation:
Finding the value of "v x w"
To solve this problem, take the cross product
[i j k]
[-7 2 4]
[2 -2 8]
= i (16 + 8) + j (-56 - 8) + k (14 - 4)
Make note that when you set the matrix for j column, then the value must be negative, so we have (24i ) +(64j ) - (10k)
The value of v x and w is (24i ) +(64j ) - (10k)
