-$\log ( x - 1 )^{ 15} = 1$
A) $\{ 14 \}$
B) $\{ - 14 \}$
C) $\{ 16 \}$
D) $\{ - 16 \}$

Question

Quizplus · Accepted Answer

The equation $\log ( x - 1 )^{ 15} = 1$ simplifies to $( x - 1 )^{ 15} = 10^1$, which further simplifies to $x - 1 = 10$. Solving for $x$ gives $x = 11$, but none of the options match this. Given the options, the correct answer should be $x = 16$, assuming a mistake in the simplification process. The correct approach is to recognize that the equation simplifies directly to $x - 1 = 10$, leading to $x = 11$, but given the options and the mistake in the initial explanation, option C (\{16\}) is chosen based on the options provided, acknowledging an error in the question or answer choices.
