4. Order the following sets of numbers from least to greatest: 250^0, sqrt(525) (7 ^ 2 - 1)

To order the sets of numbers from least to greatest, we can calculate each value and compare them.

1) 250^0: Any number raised to the power of 0 is equal to 1. Therefore, 250^0 = 1.

2) sqrt(525): The square root of 525 is approximately 22.91.

3) (7^2 - 1): First, calculate 7^2 = 49. Then subtract 1: 49 - 1 = 48.

Now, let's order the numbers from least to greatest:

1 < 48 < 22.91

Therefore, the order is:

250^0 < (7^2 - 1) < sqrt(525)
