$\mathop {\rm{A}}\limits^ \to $અને $\mathop {\rm{B}}\limits^ \to $એ સદિશો છે. નીચે આપેલા પૈકી કયું વિધાન ખોટું છે ?

$\mathop {\rm{A}}\limits^ \to .\mathop {\rm{B}}\limits^ \to \,\, = \,\,\mathop {\rm{B}}\limits^ \to .\mathop {\rm{A}}\limits^ \to $

$\mathop {\rm{A}}\limits^ \to + \mathop {\rm{B}}\limits^ \to \,\, = \,\,\mathop {\rm{B}}\limits^ \to + \mathop {\rm{A}}\limits^ \to $

$\mathop {\rm{A}}\limits^ \to \times \mathop {\rm{B}}\limits^ \to \,\, = \,\,\mathop {\rm{B}}\limits^ \to \times \mathop {\rm{A}}\limits^ \to $

$\mathop {\rm{A}}\limits^ \to \times \mathop {\rm{B}}\limits^ \to \,\, = \,\, - \mathop {\rm{B}}\limits^ \to \times \mathop {\rm{A}}\limits^ \to $

Solution is Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
