Question

Let A = {circle, square, triangle} and let B = {3, 4}. Find A X B.

Answer 1

could you explain further on this problem?

Answer 2

if A and B are supposed to be matrices, it is not possible as you have typed them in.

Answer 3

so what are the dimensions of A and B? is A 3X1 and B 1X2?

Answer 4

because that's the only combination that allows to you to multiply A and B.

Answer 5

so your answer is
\[\left[\begin{matrix} 3 cirlce & 4 circle \\3 \square & 4 \square \\3 \triangle & 4 \triangle\end{matrix}\right]\]

Answer 6

This is wrong. This is a set theory question. The operation is cartesian product.

Answer 7

{(circle, 3), (circle, 4), (square, 3), (square, 4), (triangle, 3), (triangle, 4)}

Answer 8

Do you understand the process?
