Simplifying √36 Step by Step

1. Prime factorization. — All Prime Factors of 36:

36 = 2 × 2 × 3 × 3 = 22 × 32

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.

3. Take the pairs out of the root.

√36 = √((2 × 2) × (3 × 3))

= 2 × 3

= 6

4. Check by squaring back.

6² = 6 × 6 = 36
