What is the square root of 220 simplified?
Answer
√220 = 2√55
220 = 4 × 55, and 4 = 2² is the largest perfect square that divides 220, so √220 = √4 × √55 = 2√55. Check: 2√55 ≈ 14.832, the same as √220 ≈ 14.832.
Simplifying √220 Step by Step
1. Prime factorization. — All Prime Factors of 220:
220 = 2 × 2 × 5 × 11 = 22 × 5 × 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.
| Prime factor | Times in 220 | Comes out of the root | Stays under the root |
|---|---|---|---|
| 2 | 2 | 2 | — |
| 5 | 1 | — | 5 |
| 11 | 1 | — | 11 |
3. Take the pairs out of the root.
√220 = √((2 × 2) × 5 × 11)
= 2 × √(5 × 11)
= 2√55
4. Check by squaring back.
2² × 55 = 4 × 55 = 220

FAQ
What is the square root of 220 simplified?
√220 = 2√55
Is 220 a perfect square?
No. 220 = 4 × 55: its largest perfect square factor is 4 = 2², and the factor 55 stays under the radical, so √220 = 2√55.
What is √220 as a decimal?
√220 ≈ 14.832. The decimal never ends and never repeats, so it is always rounded; the exact value is 2√55.
What is the largest perfect square that divides 220?
4 = 2². Dividing gives 220 ÷ 4 = 55, and 55 has no square factor left, so √220 = √4 × √55 = 2√55.
