√5(3√5-2√5)

To solve this expression, we can start by simplifying the expression within the parentheses.

3√5 - 2√5 equals √5.

So, the expression becomes √5(√5).

When multiplying expressions with the same base, we add the exponents. In this case, the exponent is 1/2 (since √5 is equal to 5^(1/2)).

So, the expression simplifies to √5 * √5 = √(5 * 5) = √25 = 5.

Therefore, √5(3√5-2√5) = 5.
