To compare and order the given numbers, we can arrange them in ascending or descending order.

First, we need to simplify the expression 3-√21. We can write it as:

3-√21 = 3 - 4.5826 (rounded to 4 decimal places) 1

Now, we can arrange the numbers in ascending order as follows:

-5.6 < 3 - √21 ≈ -1.5826 < 5.2 < 9 < 10’

Therefore, the numbers in ascending order are: -5.6, 3 - √21 ≈ -1.5826, 5.2, 9, and 10’.

I hope this helps!
