If `abs(veca)=2 ,abs(vecb)=5 , abs(vecaxxvecb)=8` then find value of `abs(veca*vecb)`

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

If |veca|=|vecb|=|veca+vecb|=1 then find the value of |veca-vecb|

veca*vecb=abs(vecaxxvecb) then abs(veca-vecb) is

If |veca|=5 , |veca-vecb| = 8 and |veca +vecb|=10 then find |vecb|

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca xx vecb]

If veca and vecb are two vectors, such that |veca xx vecb|=2 , then find the value of [veca vecb veca xx vecb]

If abs(vecatimesvecb)=2 and abs(veca)=1 , then abs((vecatimesvecb)-veca)^2 is

For three vectors veca, vecb and vecc , If |veca|=2, |vecb|=1, vecaxxvecb=vecc and vecbxxvecc=veca , then the value of [(veca+vecb,vecb+vecc,vecc+veca)] is equal to
