What is the square root of 170 simplified?

Answer

√170 cannot be simplified — its simplest radical form is
√170

√170 is already in simplest form — 170 has no square factor other than 1, so nothing comes out of the radical. As a decimal, √170 ≈ 13.038.

Simplifying √170 Step by Step

1. Prime factorization. — All Prime Factors of 170:

170 = 2 × 5 × 17

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.

21—2
51—5
171—17

3. Take the pairs out of the root.

√170 = √(2 × 5 × 17)

No prime appears twice, so there is no pair to take out.

√170

4. Check by squaring back.

The only perfect square dividing 170 is 1 = 1², and 1² × 170 = 170
