Answer 2

It looks like you have provided three expressions, each representing a product of three numbers. Let's calculate the values for each of them:

1. A = 5 × 7 × 13 A = 35 × 13 A = 455

2. a = 11 × 13 × 41 a = 143 × 41 a = 5843

3. a = 7 × 3 × 19 a = 21 × 19 a = 399

So, the values of A, a, and a (in the order you provided) are 455, 5843, and 399, respectively.
