Simplifying √254 Step by Step

1. Prime factorization. — All Prime Factors of 254:

254 = 2 × 127

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
1271—127

3. Take the pairs out of the root.

√254 = √(2 × 127)

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

√254

4. Check by squaring back.

The only perfect square dividing 254 is 1 = 1², and 1² × 254 = 254
