6 - square root20
-----------------
2

The square root of 20= sqrt (4*5)= sqrt4 * sqrt5= 2 sqrt5

The square root of 20= sqrt (4*5)= sqrt4 * sqrt5= 2 sqrt5

To evaluate and simplify the expression (6 - √20) / 2, we can follow these steps:

1. Find the square root of 20: √20 = √(4 * 5) = √4 * √5 = 2√5

2. Rewrite the expression with the simplified square root: (6 - 2√5) / 2

3. Divide 6 by 2: 6 / 2 = 3

4. Divide 2√5 by 2: 2√5 / 2 = √5

5. Substitute the simplified expressions back into the original expression: (3 - √5)

So, the evaluated and simplified expression is (3 - √5).
