to divide one fraction by another
invert the second fraction and then multiply first numerators and then denominators

exponents. when two terms with the same base are multiplied together
the exponents are added together

exponents. when two terms with different bases but the same exponent are multiplied together
only the bases are multiplied, the exponent stays the same

when the same base is given two exponents
the exponents are multiplied together

when exponents are multiplied together
the exponents are added to get the final result

when the exponents in parentheses have an exponent
the exponents are multiplied to get the final result
