Answer 2

To simplify the expression, let's start by applying the difference of squares formula, which states that (a - b)(a + b) = a^2 - b^2.

In this case, a = √5 and b = 2. So the expression becomes:

(√5 - 2)(√5 + 2)

Now, apply the difference of squares formula:

(√5)^2 - (2)^2

Simplify:

5 - 4

Now, subtract:

1

So the value of the expression is 1.
