Question

Dados los vectores u →=(0,1,−6);v→=(2,0,9). Calcular: M=(u+3v)⋅(4u−5v)

Answer 1

Explicación paso a paso:

U= (0,1,-6)

V= (2,0,9)

Calcular:

M= (u+3v)*(4u-5v)

M= ((0,1,-6)+3(2,0,9))*(4(0,1,-6)-5(2,0,9))

= ((0,1,-6)+(6,0,27))*((0,4-24)-(10,0,45))

= (6,1,-21)*(-10,4,-69)

= (-60, 4, 1449)

Espero Estar Bien Y Que Te Sirva, Saludos JB
