The expression is:
\[ (-0.2)^3 \cdot (-0.1)^2 \]
Step 1: Calculate the cubes and squares.
\[ (-0.2)^3 = -0.008 \]
\[ (-0.1)^2 = 0.01 \]
Step 2: Multiply the results.
\[ -0.008 \cdot 0.01 = -0.00008 \]
Ответ: -0.00008

The expression is:
\[ -6^{-1} \cdot 36^2 \cdot \left(\frac{1}{6}\right)^3 \]
Step 1: Rewrite the terms with positive exponents and simplify.
\[ -6^{-1} = -\frac{1}{6} \]
\[ 36^2 = 1296 \]
\[ \left(\frac{1}{6}\right)^3 = \frac{1^3}{6^3} = \frac{1}{216} \]
Step 2: Substitute the simplified terms back into the expression.
\[ -\frac{1}{6} \cdot 1296 \cdot \frac{1}{216} \]
Step 3: Perform the multiplication.
\[ -\frac{1296}{6 \cdot 216} = -\frac{1296}{1296} = -1 \]

The expression is:
\[ -(-1)^0 \cdot \left(-\frac{1}{3}\right)^5 \]
Step 1: Evaluate the terms with exponents.
Any non-zero number raised to the power of 0 is 1.
\[ (-1)^0 = 1 \]
\[ \left(-\frac{1}{3}\right)^5 = \frac{(-1)^5}{3^5} = \frac{-1}{243} \]
Step 2: Substitute the results back into the expression.
\[ -(1) \cdot \left(-\frac{1}{243}\right) \]
Step 3: Perform the multiplication.
\[ -1 \cdot \left(-\frac{1}{243}\right) = \frac{1}{243} \]
