exponent rules

When you multiple numbers with exponents that have the same base, you add the exponents and keep the same base. Example: three squared, times three cubed, equals three to the two plus three power; equals, three to the fifth power. When you divide numbers with the exponents that have the same base; you subtract the exponents and keep the same base. Example: three to the sixth power, divided by three squared, equals three, to the six minus two, power; equals, three to the fourth power. When you take an exponent of an exponent, you multiply the exponents. Example: three squared, cubed; equals, three to the two times three, power; equals, three to the sixth power. When you see a negative exponent, just put one over that number, with the positive exponent. Example: three to the negative two power; equals one over three squared; equals one ninth.
