Find |veca-vecb| , if two vector veca and vecb are such that |veca|=4,|vecb|=5 and veca.vecb=3

Find |veca-vecb| , if two vectors veca and vecb are such that |veca|=2,|vecb|=3 and veca.vecb=4 .

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

If |veca|=2, |vecb|=5 and |vecaxxvecb|=8 then find the value of veca.vecb

If veca and vecb are two such that |veca|=5, |vecb|=4 and |veca.vecb|=10 , find the angle between veca and vecb and hence find |vecaxxvecb|

If |veca|=sqrt(26), |vecb|=7 and |vecaxxvecb|=35, find veca.vecb
