What is the square root of 231 simplified?

Answer

√231 cannot be simplified — its simplest radical form is
√231

√231 is already in simplest form — 231 has no square factor other than 1, so nothing comes out of the radical. As a decimal, √231 ≈ 15.199.

Simplifying √231 Step by Step

1. Prime factorization. — All Prime Factors of 231:

231 = 3 × 7 × 11

2. Pair up equal primes. Each pair is a perfect square and comes out of the root as one factor; a prime without a partner stays under the radical.

31—3
71—7
111—11

3. Take the pairs out of the root.

√231 = √(3 × 7 × 11)

No prime appears twice, so there is no pair to take out.

√231

4. Check by squaring back.

The only perfect square dividing 231 is 1 = 1², and 1² × 231 = 231
