The symbol you need

The square root symbol is √. It is a standard Unicode character, so it works in browsers, documents, spreadsheets, and most learning platforms.

Write expressions clearly

For simple text, write √9 = 3. For longer expressions, use parentheses, such as √(16 + 9). This avoids confusion when you cannot use a full equation editor.

When formatting matters

In formal math work, an equation editor may look better. For quick notes, emails, and worksheets, the plain √ symbol is usually enough.

Keep formulas readable

the symbol is helpful in homework, spreadsheets, lab notes, engineering comments, and short formulas. If the audience may not know the symbol, write the word once first and then use the symbol after that. This keeps the content accurate without slowing the reader down.

Copy symbols carefully between apps

Math and science symbols can change appearance depending on the font. After pasting the symbol, check spacing, superscripts, and surrounding numbers. In plain text fields, avoid using an image of the symbol because it will not search, copy, or scale as well.
