What is the square root of 218 simplified?
Answer
√218 cannot be simplified — its simplest radical form is
√218
√218 is already in simplest form — 218 has no square factor other than 1, so nothing comes out of the radical. As a decimal, √218 ≈ 14.765.
Simplifying √218 Step by Step
1. Prime factorization. — All Prime Factors of 218:
218 = 2 × 109
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.
| Prime factor | Times in 218 | Comes out of the root | Stays under the root |
|---|---|---|---|
| 2 | 1 | — | 2 |
| 109 | 1 | — | 109 |
3. Take the pairs out of the root.
√218 = √(2 × 109)
No prime appears twice, so there is no pair to take out.
√218
4. Check by squaring back.
The only perfect square dividing 218 is 1 = 1², and 1² × 218 = 218
