1) a) 0,1\(\cdot\)60^2; 6) \(\frac{0.4^3}{50}\); B) -8\(\cdot\)\(\left\)\(\frac{1}{3}\right\)^3; r) 0,2\(\cdot\)(-2)^4;

Решение:

1. a) \( 0.1 \cdot 60^2 = 0.1 \cdot 3600 = 360 \)
2. 6) \( \frac{0.4^3}{50} = \frac{0.064}{50} = 0.00128 \)
3. B) \( -8 \cdot \left(\frac{1}{3}\right)^3 = -8 \cdot \frac{1}{27} = -\frac{8}{27} \)
4. r) \( 0.2 \cdot (-2)^4 = 0.2 \cdot 16 = 3.2 \)

Ответ: a) 360; 6) 0.00128; B) -\(\frac{8}{27}\); r) 3.2.
