How many indices does a square have?
I am not sure what the question means. However, a square is written as x2 and so it has one index whose value is 2.
How do you make the number on the outside of square root symbol?
If you are talking about writing the index on the radical symbol in LaTeX (or a front end for LaTeX like LyX), you write the index in square brackets and the argument in curly braces after the standard square root code, or more readily exemplified: \sqrt[3]{8}=2 If you are talking about writing longhand, one super scripts the index a size or two smaller prior to the radical sign. If you're word processor doesn't seem to have such an option, remember you can always write in the equivalent notation where the index is the denominator of the exponential; using the same example: 8^(1/3) = 2

Can the radicand be negative when the index is even?
Given that the radicand is part of the question, not part of the answer, you can make the radicand whatever you want it to be. However, in any given root sum, for example, sqrt(-4), if the index is even, such as it is in a square root sum, the answer will always be positive. If the index is odd, and the radicand is negative, the answer will also be negative.
Can you get 3 with 2 4's?
Yes, using sigma (sigma with index of square root of 2 and maximum value of 4) i is 9 (2+3+4) and the square root of 9 is 3 so yes, you can!
