Final answer:

To find the product of 5 and 102 mentally, multiply 5 by 100 to get 500 and multiply 5 by 2 to get 10, then add them to get 510.

Step-by-step explanation:

The student's question is how to find the product of 5 and 102 mentally.

To calculate 5⋆102 mentally, you should recognize that 102 is 100 plus 2. Multiplying 5 by 100 gives you 500, and multiplying 5 by 2 gives you 10. Adding these two products together, you get 500 + 10, which equals 510. Therefore, the product of 5 and 102 is 510.
