Let x, y, a be rational numbers, define x * y = axy4x + 5Y, and 1 * 2 = 1, try to find the value of 2 * 3

Let x, y, a be rational numbers, define x * y = axy4x + 5Y, and 1 * 2 = 1, try to find the value of 2 * 3

Because 1 * 2 = 1, so a × 1 × 24 × 1 + 5 × 2 = 1, 2A = 14, a = 7, so 2 * 3 = 7 × 2 × 34 × 2 + 5 × 3, = 4223
