Which number is the smallest among 2², 3¹, 4⁰, 5⁻¹?
Correct answer: C. 5⁻¹
- A. 4⁰
- B. 3¹
- C. 5⁻¹
- D. 2²
Explanation
To find the smallest number, calculate each expression: 2² equals 4, 3¹ equals 3, 4⁰ equals 1, and 5⁻¹ equals 1/5 or 0.2. Among these, 0.2 is the smallest. Therefore, 5⁻¹ is the correct answer. The other options, 4⁰, 3¹, and 2², evaluate to values greater than 0.2.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
