**negative exponent**expresses that the base is the denominator of a fraction instead of the numeratorThe

**multiplicative property of exponents**says that when you multiply powers with the same base you just have to add the exponentsThe

**division property of exponents**says that when you divide powers with the same base you just have to subtract the exponentsThe
