Properties of Rational Exponents

Quotient of Powers Property
When you multiply two powers with the same base, you add the exponents. (That's the product of powers property.) So when you divide two powers with the same base, you subtract the exponents. In other words, for all real numbers a, b, and c, where a ≠ 0,What you're really doing here is cancelling common factors from the numerator and denominator.
Power of a Power
To find a power of a power, multiply the exponents. This is an extension of the product of powers. Suppose you have a number raised to a power, and you multiply the whole expression by itself over and over. This is the same as raising the expression to a power.
Power of a Product
When you have a power of a product, you raise each factor to the power and then multiply them together.
Power of a Quotient
To solve a power of a quotient, you raise the numerator and the denominator to the power and then divide.
