Exponents and Subscripts

Use the ^ character (shift-6), known as a caret, to create exponents:

$x^2$

produces

$x^2$

If you have an exponent containing more than one character, group the exponent characters inside braces.

$x^21 \ne x^{21}$

produces

$x^21 \ne x^{21}$

Similarly, subscripts are created using the _ (underscore character). Again, for subscripts of more than one character, use braces to indicate where the subscript starts and stops.

$x_21 \ne x_{21}$

produces

$x_21 \ne x_{21}$

Practice: Create a document containing formulas using exponents and subscripts.
