What is the square root of 115 simplified?

Answer

√115 cannot be simplified — its simplest radical form is
√115

√115 is already in simplest form — 115 has no square factor other than 1, so nothing comes out of the radical. As a decimal, √115 ≈ 10.724.

Simplifying √115 Step by Step

1. Prime factorization. — All Prime Factors of 115:

115 = 5 × 23

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.

51—5
231—23

3. Take the pairs out of the root.

√115 = √(5 × 23)

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

√115

4. Check by squaring back.

The only perfect square dividing 115 is 1 = 1², and 1² × 115 = 115
