Simplify any square root or nth root into a √b form.
This calculator factors out the largest perfect square (or nth power) from under the radical, giving you the simplest exact form alongside the decimal approximation.
It factors the number under the radical to find perfect square factors, then pulls those out — e.g. √50 = 5√2.
No perfect square factors remain under the radical, and there's no radical in a denominator.
Yes, the same principle applies to variables raised to even powers.
