Answer

-3 Explanation 1. Use the Change of Base Formula The expression log_{2}(\frac{1}{8}) can be rewritten using the property log_{b}(a) = x \Rightarrow b^x = a. Here, 2^x = \frac{1}{8}. 2. Express \frac{1}{8} as a Power of 2 Recognize that \frac{1}{8} = 2^{-3}. 3. Equate Exponents Since 2^x = 2^{-3}, it follows that x = -3.
