How to Use and Format the Cube Root Symbol
Format ∛ according to the specific role defined for Cube Root Symbol. ∛ is U+221B CUBE ROOT. It introduces the principal cube root of the expression that follows, so ∛8 = 2. The encoded form is U+221B; preserve the full sequence, capitalization, combining marks, superscripts, and unit letters exactly as shown. For cube root symbol, placement and spacing should follow the mathematical, scientific, currency, editorial, or interface convention described on this page.
This page covers the dedicated cube-root radical ∛, not a decorative cube, the superscript-three character ³, or the general square-root sign √. When ∛ communicates an action, quantity, category, warning, or status, include nearby readable wording and an accessible name. Test cube root symbol in the actual website, document, font, export format, and assistive-technology workflow rather than accepting a merely similar glyph.
Place the radicand immediately after ∛
Use parentheses when the radicand contains several terms
Use equation markup for a radical bar that must stretch over a long expression
Keep ∛ distinct from √ and ³
Preserve the exact encoded form U+221B when publishing cube root symbol.
Use UTF-8 text or complete numeric references for ∛ rather than a visual lookalike.
Test cube root symbol rendering, copying, search, and accessibility in the final application.
