Simplify Denominator: The question prompt is asking us to simplify the expression: (1×(((1)/(2))n−1))/(((1)/(2)−1)). First, let's simplify the denominator: (1/2)−1=1/2−2/2=−1/2.
Rewrite Expression: Now, let's rewrite the expression with the simplified denominator: −211×((21)n−1).
Multiply by Reciprocal: We can simplify the expression further by multiplying the numerator by the reciprocal of the denominator: 1×((21)n−1)×(−12).
Simplify Further: Multiplying through, we get: −2×((21)n−1)=−2×(21)n+2.
Write Final Answer: The expression is now simplified, and we can write the final answer.
