Answer 2

To simplify the expression (√20 - √5)√5, we can start by simplifying the square roots:

√20 = √(4 × 5) = √4 × √5 = 2√5

Now, let's substitute the simplified value back into the expression:

(2√5 - √5)√5

Combining like terms inside the parentheses:

(2√5 - 1√5)√5 = (2 - 1)√5 × √5 = √5 × √5 = 5

Therefore, the simplified expression (√20 - √5)√5 is equal to 5. So, the correct option is B) 5.
