$\to A X \to B = 36 ˆ i + 19 ˆ j + 4 ˆ k$ $vec A X vecB=36hat i+19 hat j+4 hat k$

Explanation:

$\to A = A_{x} \cdot ˆ i + A_{j} \cdot ˆ j + A_{k} \cdot ˆ k$ $vec A=A_x* hat i+A_j* hat j+A_k* hat k$
$\to B = B_{x} \cdot ˆ i + B_{j} \cdot ˆ j + B_{k} \cdot ˆ k$ $vec B=B_x* hat i+B_j* hat j+B_k*hat k$
$cross product of two vector is determined by:$ $"cross product of two vector is determined by:"$
$\to A X \to B = ˆ i (A_{y} \cdot B_{z} - A_{z} \cdot B_{y}) - ˆ j (A_{x} \cdot B_{z} - A_{z} \cdot B_{x}) + ˆ k (A_{x} \cdot B_{y} - A_{y} \cdot B_{x})$ $vec A X vec B=hat i(A_y*B_z-A_z*B_y)- hat j(A_x*B_z-A_z*B_x)+hat k(A_x*B_y-A_y*B_x)$
$\to A X \to B = ˆ i (4 + 32) - ˆ j (- 3 - 16) + ˆ k (12 - 8)$ $vec A X vec B=hat i(4+32)-hat j(-3-16)+hat k(12-8)$
$\to A X \to B = 36 ˆ i + 19 ˆ j + 4 ˆ k$ $vec A X vecB=36hat i+19 hat j+4 hat k$
