यदि `A=hati-3hatk` तथा `B=2hati-hatj+5hatk` तब `AxxB` को प्राप्त कीजिए।

Explanation

यदि `A=A_x.hati+A_y.hati+A_z.hatk` तथा
`A=B_x.hati+B_y.hatj+B_x.hatk` तो
`AxxB=|(hati,hatj,hatk),(A_x,A_y,A_z),(B_x,B_y,B_z)|`
`=hati[0xx5-(-1)(-3)]-hatj[1xx5-2xx(-3)]+hatk[1xx(-1)-(2xx0)]`
`hatixx(-3)-hatj(5+6)-hatk=-3hati-11hatj=hatk`
