What is the square root of 238 simplified?

Answer

√238 cannot be simplified — its simplest radical form is
√238

√238 is already in simplest form — 238 has no square factor other than 1, so nothing comes out of the radical. As a decimal, √238 ≈ 15.427.

Simplifying √238 Step by Step

1. Prime factorization. — All Prime Factors of 238:

238 = 2 × 7 × 17

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.

21—2
71—7
171—17

3. Take the pairs out of the root.

√238 = √(2 × 7 × 17)

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

√238

4. Check by squaring back.

The only perfect square dividing 238 is 1 = 1², and 1² × 238 = 238
