  • On macOS, use the Character Viewer or input the Unicode hex code via `Option + Unicode`.
  • On HTML pages, use the corresponding HTML entities or numeric character references.

For example, writing `x&x00B2;` in HTML will display as \( x^{2} \).

Using Software-Specific Methods to Enter Exponents

Different software environments provide unique ways to input exponents, often through built-in tools or syntax designed for mathematical expressions.

**Microsoft Word:**

Microsoft Word supports superscript formatting and has an equation editor that allows the input of exponents in a natural mathematical style.

  • To apply superscript formatting, select the character(s) and press `Ctrl + Shift + +` or use the superscript button in the Home ribbon.
  • To insert an equation, press `Alt + =` to open the equation editor, then type expressions like `x^2` which Word converts to a formatted exponent.

**Google Docs:**

Google Docs provides a straightforward way to apply superscript:

  • Highlight the text, then choose Format > Text > Superscript.
  • Alternatively, press `Ctrl + .` (Windows/Linux) or `Command + .` (macOS) to toggle superscript.

LaTeX:

For scientific and academic documents, LaTeX is a preferred method to write exponents clearly.

  • Use the caret symbol `^` to indicate superscripts. For example, typing `x^{2}` in LaTeX will render as \( x^{2} \).
  • For single-character exponents, braces can be omitted, e.g., `x^2`.
