Question summary: Donat l'espai vectorial [real numbers squared] i [left curly bracket e subscript 1 comma e subscript 2 right curly bracket] una base. Es consideren els vectors [u subscript 1 equals # a1 asterisk times e subscript 1 plus # b1 asterisk times e subscript 2 u subscript 2 equals # a2 asterisk times e subscript 1 plus # b2 asterisk times e subscript 2] Comproveu que [left curly bracket u subscript 1 comma u subscript 2 right curly bracket] formen una base de [real numbers squared] i calculeu les components del vector [x equals # v1 times e subscript 1 plus # v2 times e subscript 2] en la base [left curly bracket u subscript 1 comma u subscript 2 right curly bracket]. Nota: si les components en la nova base són 1,2 escriviu com a solució {1,2}.
