Example: Square Root of a Positive Number
If you enter 49 into the Racine Carree Calculator, it will return 7—because the square root of 49 is 7 (√49 = 7).
Try entering different numbers above to instantly find their square roots.
Example: Square Root of a Negative Number
If you enter -81 into the Racine Carree Calculator, it will return 9i—because the square root of a negative number involves an imaginary unit (i).
Mathematically, √(-81) = √(81) × √(-1) = 9i.
This helps you understand how the calculator handles complex numbers as well.
Try it yourself, or check the example image below for reference:
👉 √(-81) = 9i
Introduction: Discover the Power of the Racine Carree Calculator
Calculating square roots can be tricky—especially when dealing with negative numbers or long decimals.
This tool takes its name from the French term for square root (racine carrée) but is designed for English-speaking users.
Even though the interface is in English, it supports those searching with French terms.
That's why we created the Racine Carree Calculator, a free online tool that makes square root calculations simple, fast, and accurate.
🔹 What Is a Square Root?
A square root is a number that, when multiplied by itself, equals the original value.
For example:
√36 = 6, because 6 × 6 = 36.
In mathematics, the square root is written using the radical symbol (√), and the number inside it is called the radicand.
Our calculator helps you interpret and evaluate these expressions with ease.
🔹 Key Concepts: Radicals, Perfect Squares, and Imaginary Roots
- Radicand: The number under the square root symbol (e.g., 25 in √25)
- Radical: The √ symbol itself
- Perfect Square: A number like 9, 16, or 49 that has an exact integer square root
- Imaginary Root: When the radicand is negative (e.g., √-81 = 9i), the result includes the imaginary unit "i"
The Racine Carree Calculator detects these cases automatically and delivers the correct output—real or complex.
🔹 How to Calculate a Square Root
There are several methods for finding square roots:
- Manual estimation using iterative averages
- Prime factorization (useful for perfect squares)
- Applying formulas for complex numbers (when inputs are negative)
- Using a scientific or online square root calculator
Our intelligent Racine Carree Calculator automatically selects the best method based on your input—whether it's a whole number, decimal, or negative value.
