Prime purpose of this lecture us to present on Laws of Exponents. Whenever we have variables which contain exponents and have equal bases, we can do certain mathematical operations to them. Those operations are called the “Laws of Exponents”. Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. Example: 8² = 8 × 8 = 64. In words: 82 could be called “8 to the second power”, “8 to the power 2” or simply “8 squared”.
