Q. Which expression is equivalent to (2026)−1 ?2−6252−70
Simplify Base: Simplify the base before applying the negative exponent.We have the expression ((26)/(20))−1. First, we need to simplify the base. Since any number to the power of 0 is 1, we have 20=1. So the expression simplifies to (26/1)−1, which is just 2^{6}^{-1}.
Apply Rule: Apply the negative exponent rule.The negative exponent rule states that a−n=an1. Applying this rule to our expression, we get 261.
Rewrite with Negative Exponent: Rewrite the expression with a negative exponent.Instead of writing the expression as a fraction, we can write it with a negative exponent: 2−6.
Check Answer Choices: Check the answer choices.We need to find the expression that is equivalent to our result. The correct answer is 2−6.
