Correct Option: C

To solve the equation \(\frac{1}{8}^{k+2}\) = 1, we need to find the value of k.

Here's how:

  1. Recognize that any non-zero number raised to the power of 0 equals 1. Therefore, for \(\frac{1}{8}^{k+2}\) to equal 1, the exponent (k+2) must be equal to 0.
  2. Set the exponent equal to 0: k + 2 = 0
  3. Solve for k: Subtract 2 from both sides of the equation: k = -2
