1. Вычислить:
- 1) $$0.04 - 49 = \frac{4}{100} - 49 = \frac{1}{25} - 49 = \frac{1}{25} - \frac{1225}{25} = -\frac{1224}{25} = -48.96$$
- 2) $$\sqrt{98 \cdot 2} = \sqrt{196} = 14$$
- 3) $$\frac{\sqrt{147}}{\sqrt{3}} = \sqrt{\frac{147}{3}} = \sqrt{49} = 7$$
- 4) $$\sqrt{(-5)^4} = \sqrt{625} = 25$$
Ответ: 1.1) -48.96; 1.2) 14; 1.3) 7; 1.4) 25
