- C.
10
Correct Answer
A. 0.1Explanation
The given expression is 10⁻¹. This means that we have a base of 10 raised to the power of -1. When a number is raised to a negative power, it means that we need to take the reciprocal of that number. Therefore, 10⁻¹ is equal to 1/10, which is equivalent to 0.1.Rate this question:
