What is the square root of 7,200 simplified?

Answer

√7,200 = 60√2

7,200 = 3,600 × 2, and 3,600 = 60² is the largest perfect square that divides 7,200, so √7,200 = √3,600 × √2 = 60√2. Check: 60√2 ≈ 84.853, the same as √7,200 ≈ 84.853.

Simplifying √7,200 Step by Step

1. Prime factorization. — All Prime Factors of 7,200:

7,200 = 2 × 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 = 25 × 32 × 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.
