If `|vec(c)|=10, |vec(b)|=2 and vec(a)*vec(b)=12`, then what is the value of `|vec(a)xxvec(b)|`?

If |vec(a)|=10 |vec(b)|=2 and vec(a).vec(b)=12 , then what is the value of |vec(a) xx vec(b)| ?

If |vec(a)|=10,|vec(b)|=2 and vec(a)*vec(b)=12 , then the value of the |vec(a)xxvec(b)| is

If (3 vec(a)-vec(b))xx(vec(a) + 3 vec(b)) =k vec(a)xxvec(b) then what is the value of k ?

Given |vec a|=10,|vec b|=2 and vec avec b=12, find |vec a xxvec b|

Let vec(a), vec(b), vec(c) be non-coplanar vectors and vec(p)=(vec(b)xxvec(c))/([vec(a)vec(b)vec(c)]), vec(q)=(vec(c)xxvec(a))/([vec(a)vec(b)vec(c)]), vec(r)=(vec(a)xxvec(b))/([vec(a)vec(b)vec(c)]) . What is the value of (vec(a)-vec(b)-vec(c)).vec(p)+(vec(b)-vec(c)-vec(a)).vec(q)+(vec(c)-vec(a)-vec(b)).vec(r) ?

If [vec(a),vec(b),vec(c)]=1, then the value of (vec(a)*(vec(b)xxvec(c)))/((vec(c)xxvec(a))*vec(a))+(vec(b)*(vec(c)xxvec(a)))/((vec(a)xxvec(b))*vec(c))+(vec(c)(vec(a)xxvec(b)))/((vec(c)xxvec(b))*vec(a)) is

(vec a xxvec b)^(2)+(vec a*vec b)^(2)=144 and |vec a|=4 then find the value of |vec b|
