Radical Simplifier

Simplify square, cube and n-th roots, reduce quotients of radicals and rationalize denominators — e.g. sqrt(50) → 5√2 and 1/sqrt(2) → √2/2 — with the exact form and a decimal value.

Frequently asked questions

What does Radical Simplifier do?

Simplify square, cube and n-th roots, reduce quotients of radicals and rationalize denominators — e.g. sqrt(50) → 5√2 and 1/sqrt(2) → √2/2 — with the exact form and a decimal value.

When would I actually use this?

Getting through a problem set: solving for the unknown, factoring an expression, and — more usefully — seeing the steps that got there.

What is the most common mistake?

Losing a solution when both sides are squared or divided by an expression. Squaring can add roots that do not satisfy the original equation, and dividing can remove one — check every answer back in the original.

How is Radical Simplifier different from Radical Equation Solver?

They sit next to each other but answer different questions: Radical Equation Solver is the one to open when you need it to solve square-root equations by isolating and squaring, then checking every candidate in the original equation to drop extraneous roots — four structured forms with step-by-step working. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Algebraic Expression Simplifier is the closest one after this: Combines like terms, expands or factors, with implicit multiplication understood (2x is 2·x). When a cancellation removes a factor, the excluded value is stated — (x²−4)/(x−2) is x+2 only for x ≠ 2, and that restriction is part of the answer.

What else is worth having open alongside it?

Boolean Algebra Simplifier and Fraction simplifier — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

The algebra is symbolic where the expression allows it and numeric otherwise, and the tool says which it used. Exact results are given as fractions or radicals rather than rounded decimals.
