What is the square root of 172 simplified?
Answer
√172 = 2√43
172 = 4 × 43, and 4 = 2² is the largest perfect square that divides 172, so √172 = √4 × √43 = 2√43. Check: 2√43 ≈ 13.115, the same as √172 ≈ 13.115.
Simplifying √172 Step by Step
1. Prime factorization. — All Prime Factors of 172:
172 = 2 × 2 × 43 = 22 × 43
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 172 | Comes out of the root | Stays under the root |
|---|---|---|---|
| 2 | 2 | 2 | — |
| 43 | 1 | — | 43 |
3. Take the pairs out of the root.
√172 = √((2 × 2) × 43)
= 2 × √43
= 2√43
4. Check by squaring back.
2² × 43 = 4 × 43 = 172
