Analysis:
Simplified by extracting 6² = 36
The simplest radical form of √72 is 6√2. This is simplified by factoring out 6² = 36 from 72.
Example
√72 = 6√2
Extracts perfect square factors (1, 4, 9, 16, 25, 36, 49, 64, 81, 100...)
Example
³√54 = 3³√2
Extracts perfect cube factors (1, 8, 27, 64, 125, 216...)
Example
⁴√16 = 2
Works for 4th roots, 5th roots, and higher order roots
Perfect squares
1, 4, 9, 16, 25, 36...

Our simplest radical form calculator uses perfect nth power factorization to simplify radicals. The calculation applies algebraic factorization principles to identify and extract perfect nth power factors (perfect squares, perfect cubes, etc.) from the radicand, reducing the radical to its simplest form. If you need to write expression in simplest radical form, this tool follows the same process taught in algebra classes.
√72 = √(36 × 2) = √36 × √2 (factor)√72 = 6 × √2 = 6√2 (extract)³√54 = ³√(27 × 2) = 3³√2 (cube root)Perfect nth powers extracted (result)The calculator finds the largest perfect nth power factor of the radicand, extracts it from under the radical, and multiplies it by any existing coefficient. The remaining radicand has no perfect nth power factors.
Shows factorization and extraction process for simplifying radicals
Simplifying radicals is based on the property that √(a × b) = √a × √b and ³√(a × b) = ³√a × ³√b. When a is a perfect nth power, we can evaluate its nth root exactly, leaving only the non-perfect factor under the radical. This process reduces the complexity of radical expressions and makes them easier to work with.
