What about (iv)

Hence W is a subspace of V3 (i). vectors (@1, 2, an) in R" are subspaces of R" (n> 3)? Example 7. Which of the following8 sets of all all a such that a 0; (i) all a such that a3 is an integer (iii) all a such that a2+4a3=0; (iv) all a such that ai+a2t... +a,=k (a given constant) Salntion () Let W=la: a E R" and ai 0}.

  • Shashi ranjan sinha thankyou
    suppose k =0....... (a1,a2, a3,...., an) and ( b1,b2, b3,...,bn) belongs to the given set and k be the scalar in R. Then, k (a1,a2, a3,...., an) + ( b1,b2, b3,...,bn) = ( ka1+b1, k...
