Pre-Algebra 22 - Exponents of One, Zero, and Negative

Professor Von Schmohawk explains exponentiation as repeated multiplication, covering the rules for multiplying and dividing exponential expressions with the same base. He discusses the meaning of exponents of one and zero, highlighting that any number to the first power is itself, and any number to the zero power is one, except zero to the zero power, which is undefined. The lecture also covers negative exponents, showing they represent the reciprocal of the base raised to the positive exponent. The video concludes with a preview of the next lecture on scientific notation.
