$$\sqrt{21} ≈ 4.58257569496$$

the 3rd root of 27 (idk how to perform the latix of cube roots) is 3

-√64 = -8

the 4th root of 25 = √5 = 2.236 ish

√40 = 6.324 ish

and - cube root of 81 = -4.326.

So the order is $$-{\sqrt{64}}$$, negative cube root of 81, 4th root of 25, 3rd root of 27, $$\sqrt{21}$$, and $$\sqrt{40}$$

also just a quick question, how do you make cube roots and fourth roots symbols ? (latex)
