Let A 1 2 B a b c d write down AX B B X A A2 B2 and AXCa

Let A = {1, 2}, B = {a, b, c, d}, write down AX B, B X A, A² , B² , and AX.(Cartesian product)

Given A = {1, 2}, B = {a, b, c, d},

then A X B = {{1, a}, {1, b}, {1, c}, {1, d}, {2, a}, {2, b}, {2, c}, {2, d}}

B X A = {{a, 1}, {a, 2}, {b, 1}, {b, 2}, {c, 1}, {c, 2}, {d, 1}, {d, 2}}

A² = {{1, 1}, {1, 2}, {2, 1}, {2, 2}}

B² = {{a, a}, {a, b}, {a, c}, {a, d}, {b, a}, {b, b}, {b, c}, {b, d}, {c, a}, {c, b}, {c, c}, {c, d}, {d, a}, {d, b}, {d, c}, {d, d}}
