How to Use and Format the Square Root Symbol

Use √ (U+221A SQUARE ROOT) as a mathematical radical, not as a decorative check mark. The radical must clearly cover or precede the complete radicand—the expression whose principal square root is being taken. In plain text, parentheses are the clearest way to show the scope of a longer expression, for example √(a + b).

For a simple value, write √9 without inserting another symbol between the radical and the radicand. For complex formulas, use mathematical markup such as MathML or LaTeX so the radical bar and grouping are unambiguous.

Write simple radicals as √9 or √x, with the radicand immediately following the radical sign.
Use parentheses in plain text when the radicand contains more than one term, such as √(a + b).
Interpret √x as the principal square root unless the surrounding notation defines another branch.
Use ∛ for a cube root and another indexed radical when the root is not a square root.
Do not substitute ✓, the letter v, or an image for the Unicode square-root character.
Use MathML, LaTeX, or an equation editor when a radical bar must extend across a complex expression.

Square Root Symbol Examples

√0 = 0
√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5
√36 = 6
√49 = 7
√64 = 8
√81 = 9
√2 ≈ 1.41421

Common Square Root Symbol Mistakes

Do not write √9 = ±3; the principal square root is 3, while x² = 9 has the two solutions x = ±3.
Do not assume √(x²) = x for every real x; the principal value is
x
.
Do not omit parentheses when the radicand could be unclear; distinguish √(a + b) from √a + b.
Do not use √ for a cube root; use ∛ when a cube-root symbol is required.
Do not replace √ with a letter v or with ✓.
Do not assume a negative number has a real square root without specifying complex numbers.
Do not confuse √ (U+221A) with a check mark.
Do not end the radical bar before all terms that belong to the radicand.

More About the Square Root Symbol

The square root symbol √ is a Unicode text character, not an image. The square root symbol is the radical sign used to show a root operation. Without another index, it normally means the principal square root. Because it remains selectable text, it can be copied into documents, messages, spreadsheets, source code, usernames, captions, and other fields that support Unicode. Its appearance can change with the active font or operating system, while the stored character remains U+221A (SQUARE ROOT).

Supporting searches such as “copy and paste square root symbol”, “how to type the square root symbol”, and “square root symbol keyboard” usually describe the same core task from different angles: identifying the correct character, copying it, or learning how to enter it with a keyboard. This page keeps those intents together so you do not need separate pages for small wording differences. Use the copy control for the fastest method, then check the platform rows when you need a repeatable shortcut on a specific device or app.

Queries such as “square root symbol on computer keyboard” and “square root symbol on keyboard phone” are covered by the keyboard, application, and character-code sections. The Windows and Mac instructions explain practical input methods, while the Microsoft Word and Google Docs rows cover document editing. Unicode, HTML, hexadecimal, and CSS values are listed separately so developers can insert the exact character without confusing it with a similar-looking mark.

Choose √ when its documented meaning matches the surrounding text, and compare the related-symbol links below when another character may be more precise. Spacing and visual style can vary by context, so follow the style guide of the document or platform. For example: √9 = 3
