$\to a x \to b = 29 i + 6 j + 29 k$ $veca x vecb=29i+6j+29k$

Explanation:

$The cross product of two vector , \to a and \to b is given by:$ $"The cross product of two vector ," vec a and vec b " is given by:"$
$i,j,k are unit vectors$ $"i,j,k are unit vectors"$
$\to a x \to b = i (a_{j} b_{k} - a_{k} b_{j}) - j (a_{i} b_{k} - a_{k} b_{i}) + k (a_{i} b_{j} - a_{j} b_{i})$ $veca x vecb=i(a_jb_k-a_kb_j)-j(a_ib_k-a_kb_i)+k(a_ib_j-a_jb_i)$
$\to a x \to b = i (2.7 + 3.5) - j (2.9 - 8.3) + k (2.7 + 3.5)$ $veca x vecb=i(2.7+3.5)-j(2.9-8.3)+k(2.7+3.5)$
$\to a x \to b = i (29) - j (- 6) + k (29)$ $veca xvec b=i(29)-j(-6)+k(29)$
$\to a x \to b = 29 i + 6 j + 29 k$ $veca x vecb=29i+6j+29k$
