Math Problem Statement

(1/2)-³

Solution

To evaluate (12)3(\frac{1}{2})^{-3}, you can use the property of exponents that states an=1ana^{-n} = \frac{1}{a^n}.

So,

(12)3=1(12)3\left(\frac{1}{2}\right)^{-3} = \frac{1}{\left(\frac{1}{2}\right)^3}

Now calculate (12)3\left(\frac{1}{2}\right)^3:

(12)3=1323=18\left(\frac{1}{2}\right)^3 = \frac{1^3}{2^3} = \frac{1}{8}

Thus,

1(12)3=118=8\frac{1}{\left(\frac{1}{2}\right)^3} = \frac{1}{\frac{1}{8}} = 8

Therefore, (12)3=8(\frac{1}{2})^{-3} = 8.
