Question

find A×B, A×A, B×A. A={2,-2,3}and B={1,-4}​

Answer 1

Answer:-

Given A={2,-2,3}

B={1,-4}

Now,

A× B = {2,-2,3} × {1,-4} = {2,1} ,{2,-4},{-2,1},{-2,-4}, {3,1},   { 3,-4} ...

B ×A= {1,-4}×{2,-2,3}   ={ 1,2}, {1,-2},{1,3},{-4,2},{-4,-2},{-4,3}

A×A = {2,-2,3}  ×{2,-2,3}   = {2,2},{2-2},{2,3},{-2,2},{-2,-2} , {-2,3} ,{3,2},{3, -2}, {3,3}...
