Hello!

√28x³y³ is equal to
2xy√(7xy)

We can find this solution through the following steps.

  1. Rewriting the equation by factoring 4 from 28, factoring out x², and factoring out y²
  2. We then can rewrite 4 as 2² in our equation, leaving us with
    \sqrt{2^(2)*7*(x^(2)x)*y^(2)y }
  3. We will then move our x and 7, and rewrite
    2^(2)*x^(2)* y^(2) as
    (2xy)^(2)
  4. We can then pull the terms from the radical leaving us with
    2xy√(7xy)
