To evaluate 1 to the power of 3, we use the concept of exponentiation. When any number is raised to a power, it means that this number is multiplied by itself as many times as indicated by the power. In this case, we have:
13 = 1 × 1 × 1
So, when we multiply 1 by itself three times, we still get 1. Therefore, the answer is:
13 = 1
This demonstrates a basic property of the number 1 in mathematics: no matter how many times you multiply 1 by itself, the result will always be 1.
