| Platform | Shortcut | How to Use |
|---|---|---|
| Windows | Alt + 251 (on numeric keypad) | Hold Alt, type 251, then release. |
| macOS | Option + V (works in some apps, not Docs) | Alternatively, use Control + Cmd + Space, search “square root”. |
| Ubuntu/Linux | Ctrl + Shift + U, then 221A, press Enter | Hold Ctrl + Shift + U, type 221A, press Enter. |
🎯 Tip: On Mac and Linux, it’s often easier to use the Special Characters menu or equation tool.
