Answer 2

To simplify the expression, let's calculate each part step by step:

1. Simplify the numerator: 8 - 2√12 = 8 - 2√(4 * 3) = 8 - 2√4 * √3 = 8 - 2 * 2 * √3 = 8 - 4√3.

2. Simplify the denominator: √3 - 2 + 7/2 - 0.3.

Now, combining the simplified numerator and denominator, the expression becomes:

(8 - 4√3) / (√3 - 2 + 7/2 - 0.3).

To perform further calculations, we need to find a common denominator for the terms in the denominator:

Common denominator = 2.

√3 - 2 = (2√3 - 4)/2. 7/2 = 3.5. 0.3 = 0.3 * 2/2 = 0.6/2.

Now the expression becomes:

(8 - 4√3) / ((2√3 - 4 + 3.5 - 0.6)/2).

Now let's simplify the denominator further:

(8 - 4√3) / ((2√3 - 0.5)/2).

Now, to eliminate the fraction in the denominator, we multiply the expression by its reciprocal:

(8 - 4√3) * (2 / (2√3 - 0.5)).

Now, let's simplify the expression:

= (8 - 4√3) * (2 / (2√3 - 0.5)) = (8 - 4√3) * (2 / ((2√3 - 0.5) * (2√3 + 0.5))). = (8 - 4√3) * (2 / (4 * 3 - 0.5^2)). = (8 - 4√3) * (2 / (12 - 0.25)). = (8 - 4√3) * (2 / 11.75). = (16 - 8√3) / 11.75.

So, the simplified expression is (16 - 8√3) / 11.75.
