Simplify Radicals with Radical Form Calculator

The simplify feature of our radical form calculator reduces radicals to their simplest form by extracting perfect powers and simplifying coefficients.

Example: Simplify √72

√72 = √(36 × 2) = √36 × √2 = 6√2

Steps:

1. Factor 72: 2³ × 3²
2. Group perfect squares: (3²) × (2 × 2)
3. √(3² × 2 × 2) = 3 × √(2 × 2) = 3 × 2 × √1 = 6√2

Our radical form calculator handles:

  • Square roots, cube roots, higher roots
  • Variables under radicals
  • Mixed radicals (coefficient + radical)
  • Nested radicals
  • Negative radicands (with imaginary results)

Rationalize Denominator Using Radical Form Calculator

Rationalizing removes radicals from the denominator. Our radical form calculator handles single radicals, binomial denominators, and complex cases.

Example: Rationalize 1/√2

1/√2 × √2/√2 = √2/2

Conjugate Method for Binomials:

3/(√3 - 1) × (√3 + 1)/(√3 + 1) = 3(√3 + 1)/(3 - 1) = 3(√3 + 1)/2

Convert Between Radical and Exponent Form

Our radical form calculator seamlessly converts between forms:

  • √x → x^(1/2)
  • ∛x → x^(1/3)
  • x^(1/n) → nth root of x
  • x^(m/n) → (nth root of x)^m

Perform Operations on Radicals

Add, subtract, multiply, and divide radicals with like terms. Our radical form calculator requires same index and radicand for addition/subtraction.

Example: 2√3 + 3√3 = 5√3

Multiply: (2√3)(3√2) = 6√6
Divide: 6√15 / 2√3 = 3√5

Frequently Asked Questions

What is radical form?

Radical form uses the √ symbol to represent roots. Our radical form calculator converts and simplifies all radical expressions with full explanations.

When do we rationalize denominators?

Standard mathematical convention requires rational (non-radical) denominators. The radical form calculator automates this process.

Can this handle cube roots and higher?

Yes! Our radical form calculator supports ∛, fourth roots, and any nth root with complete simplification.

What about negative numbers under radicals?

Square roots of negatives yield imaginary results (e.g., √(-4) = 2i). Our radical form calculator handles complex numbers when needed.
