Order the following sets of numbers from least to greatest:

250^0, √525, (7^2-1)

250^0, (7^2-1), √525

Explanation:
250^0 = 1, since any number to the power of 0 is always 1.
√525 is the square root of 525, which is approximately 22.91.
(7^2-1) = (49-1) = 48.

So the order from least to greatest is: 1, 48, 22.91.
