    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
  2. 3)
    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.
    \[ -\frac{1296}{6 \cdot 216} = -\frac{1296}{1296} = -1 \]

    Ответ: -1
  3. и)
    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.
    \[ -1 \cdot \left(-\frac{1}{243}\right) = \frac{1}{243} \]

    Ответ: 1/243
