What does the little number inside the "v" of the square root sign mean?

example:
suare root of -8 with a little "3" in the "v"
------------------
If there is no number, it's a square root.
If it's a 3, it's a cube root. 4 is the 4th root, etc.
-------------------
square root of -8 with a little "3" in the "v"
That's the cube root of -8, or
The cube root of -8 = -2 because (-2)*(-2)*(-2) = -8 (3 of them multiplied)

Is the problem ??? If so, then this reads: "the cubed root of -8"
What this is asking is: what number multiply by itself 3 times will give you -8?
Since , this shows us that -2 multiplied by itself 3 times is -8.
So

That "little v" is really a "little r" and means root.
If there is no number it means square root.
If there is a 3, it means cube root, or 3rd root.

Your Problem
cube root of -8 is -2 because (-2)(-2)(-2) = -8
