What is the square root of 720 simplified?
Answer
√720 = 12√5
720 = 144 × 5, and 144 = 12² is the largest perfect square that divides 720, so √720 = √144 × √5 = 12√5. Check: 12√5 ≈ 26.833, the same as √720 ≈ 26.833.
Simplifying √720 Step by Step
1. Prime factorization. — All Prime Factors of 720:
720 = 2 × 2 × 2 × 2 × 3 × 3 × 5 = 24 × 32 × 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 720 | Comes out of the root | Stays under the root |
|---|---|---|---|
| 2 | 4 | 22 | — |
| 3 | 2 | 3 | — |
| 5 | 1 | — | 5 |
3. Take the pairs out of the root.
√720 = √((2 × 2) × (2 × 2) × (3 × 3) × 5)
= 2 × 2 × 3 × √5
= 12√5
4. Check by squaring back.
12² × 5 = 144 × 5 = 720
