To simplify the expression, we can use the distributive property and combine like terms.

First, let's simplify the first part of the expression: (2^9 + 2^7 + 1)

2^9 = 512
2^7 = 128

So, (2^9 + 2^7 + 1) = (512 + 128 + 1) = 641

Now, let's simplify the second part of the expression: (2^23 - 2^21 + 2^19 - 2^17 + 2^14 - 2^10 + 2^9 - 2^7 + 1)

2^23 = 8,388,608
2^21 = 2,097,152
2^19 = 524,288
2^17 = 131,072
2^14 = 16,384
2^10 = 1,024

So, (2^23 - 2^21 + 2^19 - 2^17 + 2^14 - 2^10 + 2^9 - 2^7 + 1) = (8,388,608 - 2,097,152 + 524,288 - 131,072 + 16,384 - 1,024 + 512 - 128 + 1) = 6,711,521

Finally, let's multiply the two simplified parts together:

641 * 6,711,521 = 4,305,019,361
