Lesson Summary:

In this lesson, the instructor explains why any number to the zero power is equal to one. They use the example of three to the zero power being one and demonstrate a logical deduction of this concept. By dividing 27 by 3, then 9 by 3, and so on, they show that the exponent decreases by one each time until it reaches zero. This pattern helps students understand why any number to the zero power equals one.
