Answer 1

Если не понимаешь ято за цифра ² это показывает то что это число нужно умножить на точно такое же число

Answer 2

Sure, I can help you solve these mathematical expressions step by step:

1. $(-0.2)^3 + 0.3 : (-0.1)$ First, calculate $(-0.2)^3$ which is -0.008. Then, calculate $0.3 : (-0.1)$ which is -3. Now add the two results: $-0.008 + (-3) = -3.008$.

2. $(-1/3 - 1/6 + 0.5)^3 - 3$ First, simplify the expression inside the parentheses: $-1/3 - 1/6 + 0.5 = 0.5 - 0.1667 = 0.3333$. Now cube this result: $0.3333^3 \approx 0.03704$. Finally, subtract 3: $0.03704 - 3 \approx -2.96296$.

3. $(0.1 - 1) \times (-2)^3$ First, calculate $0.1 - 1 = -0.9$. Then calculate $(-2)^3 = -8$. Multiply the two results: $-0.9 \times -8 = 7.2$.

4. $-1.5 \times 0.6 - 1^5 - 0.1$ First, calculate $-1.5 \times 0.6 = -0.9$. Then calculate $1^5$ which is 1. Finally, subtract 0.1: $-0.9 - 1 - 0.1 = -2$.

5. $-2/5 + 0.3 \times 2 - 1 : 5$ First, calculate $-2/5 = -0.4$. Then calculate $0.3 \times 2 = 0.6$. Now calculate $1 : 5 = 0.2$. Add the three results: $-0.4 + 0.6 + 0.2 = 0.4$.

6. $(-0.5)^2 + 0.5^2 + 1 : 2$ First, calculate $(-0.5)^2 = 0.25$ and $0.5^2 = 0.25$. Then calculate $1 : 2 = 0.5$. Add the three results: $0.25 + 0.25 + 0.5 = 1$.

Please double-check my calculations to ensure accuracy.
