To solve this puzzle, we need to identify the pattern or rule that connects the numbers.

Given:

7 49 ?
8 ? 512
Missing Number in This Math Puzzle

1. The first row has the numbers 7, 49, and ?.
2. The second row has the numbers 8, ?, and 512.

The number 49 is 7 squared (7 * 7 = 49). Following this pattern, we need to find the numbers that fit the second row.

Let’s apply the same pattern to the second row:
The number 512 is 8 cubed (8 * 8 * 8 = 512).

Thus, the missing number in the first row should be 7 cubed (7 * 7 * 7), and the missing number in the second row should be 8 squared (8 * 8).

Calculations:
7 cubed is 343 (7 * 7 * 7 = 343).
8 squared is 64 (8 * 8 = 64).

So the complete grid should be:

7 49 343
8 64 512

Therefore, the missing numbers are 343 and 64.
