To solve this expression, we can follow the order of operations (PEMDAS/BODMAS):

First, let's simplify the exponentiation:
2^11.51 = 2,000.65 (approximately)
2^10.27 = 1,364.99 (approximately)
2^9 = 512

Now, let's substitute these values back into the expression:
2,000.65 - 1,364.99 / 512 * 0.25

Next, let's perform the division:
1,364.99 / 512 = 2.667 (approximately)

Now, let's substitute this value back into the expression:
2,000.65 - 2.667 * 0.25

Next, let's perform the multiplication:
2.667 * 0.25 = 0.66675 (approximately)

Now, let's substitute this value back into the expression:
2,000.65 - 0.66675

Finally, let's subtract:
2,000.65 - 0.66675 = 1,999.98325 (approximately)

Therefore, 2^11.51 - 2^10.27 / 2^9 * 0.25^2 is approximately equal to 1,999.98325.
