$$\sqrt{0.04} - (\sqrt{7} - 2\sqrt{2})(\sqrt{8} + \sqrt{7}) = 0.2 - (\sqrt{7} - 2\sqrt{2})(2\sqrt{2} + \sqrt{7})$$
$$= 0.2 - (\sqrt{7} \cdot 2\sqrt{2} + \sqrt{7} \cdot \sqrt{7} - 2\sqrt{2} \cdot 2\sqrt{2} - 2\sqrt{2} \cdot \sqrt{7})$$
$$= 0.2 - (2\sqrt{14} + 7 - 8 - 2\sqrt{14})$$
$$= 0.2 - (7 - 8)$$
$$= 0.2 - (-1)$$
$$= 0.2 + 1$$
$$= 1.2$$
Ответ: 1.2
