$A X B = - 29 ˆ i + 5 ˆ j + 27 ˆ k$ $A X B=-29 hat i+5 hat j+27 hat k$

Explanation:

$A X B = ˆ i (2 \cdot 3 - 5 \cdot 7) - ˆ j (5 \cdot 3 - 5 \cdot 4) + ˆ k (5 \cdot 7 - 2 \cdot 4)$ $A X B=hat i(2*3-5*7)-hat j(5*3-5*4)+hat k(5*7-2*4)$

$A X B = ˆ i (6 - 35) - ˆ j (15 - 20) + ˆ k (35 - 8)$ $A X B=hat i(6-35)-hat j(15-20)+hat k(35-8)$

$A X B = - 29 ˆ i + 5 ˆ j + 27 ˆ k$ $A X B=-29 hat i+5 hat j+27 hat k$
