Answer 2

To simplify the expression, let's assume that "a" is a non-negative real number.

1. -√a: This means the negative square root of "a."

2. √a(1-√a): Here, we multiply the square root of "a" by the quantity (1 - √a).

3. √a(√a - 1): In this case, we multiply the square root of "a" by the quantity (√a - 1).

4. a√a: This expression represents the product of "a" and the square root of "a."

Please note that without a specific value for "a," it's not possible to determine the exact numerical value of the expressions. However, we can still work with the algebraic representation.
