What is the square root of 1,280 simplified?
Answer
√1,280 = 16√5
1,280 = 256 × 5, and 256 = 16² is the largest perfect square that divides 1,280, so √1,280 = √256 × √5 = 16√5. Check: 16√5 ≈ 35.777, the same as √1,280 ≈ 35.777.
Simplifying √1,280 Step by Step
1. Prime factorization. — All Prime Factors of 1,280:
1,280 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 5 = 28 × 5
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 1,280 | Comes out of the root | Stays under the root |
|---|---|---|---|
| 2 | 8 | 24 | — |
| 5 | 1 | — | 5 |
3. Take the pairs out of the root.
√1,280 = √((2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × 5)
= 2 × 2 × 2 × 2 × √5
= 16√5
4. Check by squaring back.
16² × 5 = 256 × 5 = 1,280
