What is the square root of 105 simplified?

Answer

√105 cannot be simplified — its simplest radical form is
√105

√105 is already in simplest form — 105 has no square factor other than 1, so nothing comes out of the radical. As a decimal, √105 ≈ 10.247.

Simplifying √105 Step by Step

1. Prime factorization. — All Prime Factors of 105:

105 = 3 × 5 × 7

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.

31—3
51—5
71—7

3. Take the pairs out of the root.

√105 = √(3 × 5 × 7)

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

√105

4. Check by squaring back.

The only perfect square dividing 105 is 1 = 1², and 1² × 105 = 105
