In this video we look at a difficult problem pertaining to Powers with Negative Exponents. This is the second part of a 2 part example.

In this video we look at a difficult problem pertaining to Powers with Negative Exponents. This is the first part of a 2 part example.

The following video looks at simplifying powers that include a zero exponent.

KEY CONCEPTS:- multiplying powers with the same base, add the exponents.- if bases are NOT the same your CAN'T simplify the expression

KEY CONCEPTS:- Whenever you have an exponent followed by another exponent, keep the base and multiply the two exponents

KEY CONCEPT:ANY power with an exponent of zero, regardless if the BASE of the power is a number or a variable is equal to 1a^0=1999^0=1
