AskSia simplifies any radical expression step-by-step: factor out perfect squares (or cubes, or higher powers), rationalize the denominator (including with conjugates), and combine like radicals. Every step is named, so you can apply the same method on your next problem.
The AskSia radical expression simplifier is an AI tool that handles every kind of radical simplification: factoring out perfect squares from square roots (like √48 becoming 4√3), factoring perfect cubes from cube roots (like ∛54 becoming 3∛2), rationalizing monomial denominators (multiplying top and bottom by the radical), rationalizing binomial denominators (multiplying by the conjugate), and combining like radicals across multi-term expressions. Each step is named (perfect-square factor, conjugate, like-radical), so the method transfers to your next problem.
Most radical mistakes come from forgetting which step comes next: factor first, rationalize next, then combine. AskSia walks through the canonical order and explains each move.
Before anything else, AskSia factors the radicand and pulls out perfect squares (or perfect cubes for cube roots). √72 becomes √(36 × 2), which becomes 6√2. The prime factorization or perfect-power extraction is shown explicitly.
When a radical is in the denominator, AskSia multiplies top and bottom by the radical (for monomial denominators) or by the conjugate (for binomial denominators like 2 + √3). The conjugate move is named explicitly when used.
Radicals with the same radicand can be combined: 3√2 + 5√2 = 8√2. AskSia identifies like radicals across multi-term expressions and combines them, just like combining like terms.
For cube roots and fourth roots, AskSia factors out perfect cubes or fourth powers, the analog of the square root method. The same principles extend, just with a different perfect power.
AskSia converts between radical form and rational exponent form on demand: ∛x² is the same as x^(2/3). Useful for calculus prep where rational exponents are needed for differentiation.
Square roots of negative numbers are handled with i = √(-1). √(-25) becomes 5i. AskSia explains the imaginary unit and keeps complex results in standard a + bi form.
Snap a photo, paste the expression, or type it into the built-in calculator. AskSia reads radical notation (√, ∛, fractional exponents) and LaTeX.
AskSia factors out perfect powers, rationalizes the denominator if needed, then combines like radicals. Each step is named so you can apply the method on the next problem.
The final simplified expression appears, with a check showing it equals the original numerically. Ask follow-up questions or generate practice problems.

First-time radical problems: simplify √24, √50, √72. AskSia factors the radicand and pulls out the perfect square clearly, with each step labeled.
Rationalizing denominators with monomial radicals (multiply by √a / √a) and binomial radicals (multiply by the conjugate). AskSia names each move.
Multi-term radical expressions like 3√2 + 5√8 - √18. AskSia simplifies each term first, then identifies like radicals (√2 in this case) and combines them.
Cube root and fourth root problems from College Algebra and Pre-Calc. AskSia factors out perfect cubes or fourth powers, analogous to the perfect-square method.
Converting ∛x² to x^(2/3) and back, useful when transitioning from algebra to calculus where rational exponents are standard for differentiation.
Radical simplification is a regular SAT and ACT topic. After any solve, generate practice problems at the right difficulty level for your target exam.
