Simplifying √290 Step by Step

1. Prime factorization. — All Prime Factors of 290:

290 = 2 × 5 × 29

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
291—29

3. Take the pairs out of the root.

√290 = √(2 × 5 × 29)

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

√290

4. Check by squaring back.

The only perfect square dividing 290 is 1 = 1², and 1² × 290 = 290
