1)
$3000 \times (0.2) { }^{3} - ( - 2) {}^{6}$
2)
$\frac{1.6}{(0.4) {}^{2} } - ( - 3) {}^{3}$

Answer 1

$1. \ 3000 \cdot (0,2)^3 - (-2)^6 = 3 \cdot 10^3 \cdot (2 \cdot 10^-^1)^3 - 64 = \\ = 3 \cdot 10^3 \cdot 2^3 \cdot 10^-^3 - 64 = 3 \cdot 8 - 64 = -40 \\ 2. \ \frac{1,6}{(0,4)^2} - (-3)^3 = \frac{1,6}{0,16} - 27 = 10 - 27 =-17$
