2. Вычислите a) \(\sqrt{0.36} + \sqrt{0.01}\) б) \(\frac{1}{8} \sqrt{64} - 1\) в) \(-3\sqrt{0.49} + 2.6\) г) \(0.4 \sqrt{0.04}\) д) \(\sqrt{(3.8)^2}\) e) \(\sqrt{(-1.3)^2}\)

a) \(\sqrt{0.36} + \sqrt{0.01} = 0.6 + 0.1 = 0.7\) б) \(\frac{1}{8} \sqrt{64} - 1 = \frac{1}{8} \cdot 8 - 1 = 1 - 1 = 0\) в) \(-3\sqrt{0.49} + 2.6 = -3 \cdot 0.7 + 2.6 = -2.1 + 2.6 = 0.5\) г) \(0.4 \sqrt{0.04} = 0.4 \cdot 0.2 = 0.08\) д) \(\sqrt{(3.8)^2} = |3.8| = 3.8\) e) \(\sqrt{(-1.3)^2} = |-1.3| = 1.3\)
