1. Expression such as 7 + √3 and 7 - √3 are called Radical Expression.
2. To simplify √3 (√2 + 7), we use the associative property.
3. The product of square root conjugates is an expression that does not contain a radical.
4. The product of the square root of two nonnegative numbers is equal to the square root of the product of these numbers.
