Diketahui : Ditanyakan : Hasil kali silang ? Jawab : Perkalian silang antara dua vektor a dan b , menghasilkan sebuah vektor sehingga disebut perkalian vektor. Hasil kali silang vektor a dan vektor b didapatkan : Dengan demikian,hasil kali silang adalah Sepertinya ada kesalahan pada bagian ini, sehingga tidak terdapat jawaban yang tepat.

Diketahui :

table attributes columnalign right center left columnspacing 0px end attributes row cell a with rightwards arrow on top space end cell equals cell space 3 straight i with hat on top space minus space 2 straight j with hat on top space minus space 3 straight k with hat on top end cell row cell b with rightwards arrow on top space end cell equals cell space minus 2 blank with hat on top straight i space minus space straight j with hat on top space plus space 2 straight k with hat on top end cell end table 

Ditanyakan : Hasil kali silang open parentheses a with rightwards arrow on top space cross times space b with rightwards arrow on top close parentheses?

Jawab :

Perkalian silang antara dua vektor a dan b open parentheses a with rightwards arrow on top space cross times space b with rightwards arrow on top close parentheses, menghasilkan sebuah vektor sehingga disebut perkalian vektor. Hasil kali silang vektor a dan vektor b didapatkan :

Dengan demikian, hasil kali silang begin bold style straight left parenthesis a with italic rightwards arrow on top straight space straight cross times straight space b with italic rightwards arrow on top straight right parenthesis end style adalah negative 7 i with hat on top space minus 7 space k with hat on top.
