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
The symbol used before a number to make it a label is a hash sign (#).
It is 221A + Alt X
make a rectangle that covers 8 square units inside and has a perimeter of 12 units around the outside
Select the other number so that it is bigger than the square number!
press alt and then v (at least it worked on mine)
the square root symbol. that would make it 1,/2 (i don't know how to make a square root symbol, sorry) but since the numbers are next to each other it is assumed that they are being multiplied and the square root of 2 is approximately 1.414 right in between 1 and 2 :)
you make a square number by multiplying a number times itself.
The symbol used before a number to make it a label is a hash sign (#).
A square root sign.
an improper fraction is a fraction that's numerator is larger than its denominator that's what an improper fraction is.Put the numerator in side the division symbol, then put the Divisor outside the symbol. Once you have your answer you put the answer (DON'T ADD THE REMAINDER) as the whole number. Then put the remainder as the numerator and the number outside the symbol, put it as your denominator.
It is 221A + Alt X

Most processors have a special symbol key; on Microsoft Word go to "INSERT" then "SYMBOLS" and look for it there

All numbers can make a square. Every real number makes a positive real square. Every rational number makes a rational square. Every integer makes a perfect square.
