Nth root symbol copy and paste — every format
Whatever you're pasting into — a browser, LaTeX document, spreadsheet, or CSS file — grab the exact nth root symbol format it expects, including the one index (4) that has a real character of its own.

Need a whole equation, not just the symbol?
The equation writer builds a copyable nth-root expression for any index you choose — like ⁵√(32) — instead of a bare symbol.
Open the equation writerWriting software instead of a document?
See Unicode escapes, LaTeX, and the actual nth-root formula across JavaScript, Python, Excel, and more — plus where odd and even indexes diverge on negative numbers.

What is the Unicode code point for the nth root symbol?
There isn't one — n varies, so there's no single dedicated character the way square root (U+221A) and cube root (U+221B) have their own. The one exception is the 4th root, ∜, which is U+221C. Any other index is composed from a superscript digit (or digits) followed by the base radical, U+221A.
How do I add an nth root symbol in HTML?
For the 4th root specifically, use the numeric entity ∜ or paste ∜ directly. For any other index, combine a superscript-digit entity — ⁵ for 5 (⁵), for example — immediately before √ (√), or just paste the composed text from the equation writer.
What's the LaTeX command for an nth root?
\sqrt[n]{x} for a variable index, or \sqrt[5]{x}, \sqrt[12]{x}, etc. for a specific one — replace the bracketed number with whatever index you need. Dropping the brackets entirely, \sqrt{x}, gives a plain square root. Works in LaTeX, MathJax, and KaTeX.
How do I calculate an nth root in Excel or Google Sheets?
Neither app has a built-in NTHROOT function. Use =A1^(1/B1), where A1 is the number and B1 is the index. If A1 can be negative and B1 is odd, use =SIGN(A1)*ABS(A1)^(1/B1) instead — a plain =A1^(1/B1) returns a #NUM! error for a negative base whenever the exponent isn't a clean reciprocal of an odd integer.
Is there a Windows alt code for the nth root symbol?
Not for a combined symbol with an arbitrary index — Windows' legacy Alt-codes only cover a fixed set of characters, and a composed ⁿ√ isn't one of them. The 221C + Alt + X trick does work for the 4th root specifically, the same way 221A + Alt + X produces the plain radical. For any other index, generate the symbol with the equation writer and copy it.
