Laws of Exponents Part 1

This video explains why we add the exponent when we multiply two expressions with the same base. I have provided the explanation below in English, but the video is in Filipino.

The Exponential Notation Before we learn the laws of exponents, we first review the exponential notation.   Consider the following examples.

  1. 2^3 = 2 \times 2 \times 2.
  2. 3^2 = 3 \times 3
  3. a^4 = a \times a \times a \times a.

If you can observe, the exponent is the number of times the base is multiplied. In other words, 6^{20} means multiplying 6 twenty times.
