Solve (2)^-1*(-3)^-1*(-1)^-1

$$( 2 ) ^ { - 1 } \cdot ( - 3 ) ^ { - 1 } \cdot ( - 1 ) ^ { - 1 }$$

Evaluate

$$\frac{1}{6}\approx 0.166666667$$

Solution Steps

Calculate 2 to the power of -1 and get \frac{1}{2}.

$$\frac{1}{2}\left(-3\right)^{-1}\left(-1\right)^{-1}$$

Calculate -3 to the power of -1 and get -\frac{1}{3}.

$$\frac{1}{2}\left(-\frac{1}{3}\right)\left(-1\right)^{-1}$$

Multiply \frac{1}{2} and -\frac{1}{3} to get -\frac{1}{6}.

$$-\frac{1}{6}\left(-1\right)^{-1}$$

Calculate -1 to the power of -1 and get -1.

$$-\frac{1}{6}\left(-1\right)$$

Multiply -\frac{1}{6} and -1 to get \frac{1}{6}.

$$\frac{1}{6}$$

Factor

$$\frac{1}{2 \cdot 3} = 0.16666666666666666$$
