What is the square root of 200 simplified?

Answer

√200 = 10√2

200 = 100 × 2, and 100 = 10² is the largest perfect square that divides 200, so √200 = √100 × √2 = 10√2. Check: 10√2 ≈ 14.142, the same as √200 ≈ 14.142.

Simplifying √200 Step by Step

1. Prime factorization. — All Prime Factors of 200:

200 = 2 × 2 × 2 × 5 × 5 = 23 × 52

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.

√200 = √((2 × 2) × (5 × 5) × 2)

= 2 × 5 × √2

= 10√2

4. Check by squaring back.

10² × 2 = 100 × 2 = 200

FAQ

What is the square root of 200 simplified?

√200 = 10√2

Is 200 a perfect square?

No. 200 = 100 × 2: its largest perfect square factor is 100 = 10², and the factor 2 stays under the radical, so √200 = 10√2.

What is √200 as a decimal?

√200 ≈ 14.142. The decimal never ends and never repeats, so it is always rounded; the exact value is 10√2.

What is the largest perfect square that divides 200?

100 = 10². Dividing gives 200 ÷ 100 = 2, and 2 has no square factor left, so √200 = √100 × √2 = 10√2.
