Evaluating Numbers with Rational Exponents by using.
Convert radical notation to rational exponent notation, and vice-versa. Extend the properties of integer exponents to rational exponents and use them to simplify expressions. Common Core: HSN-RN.A.2 Radical Equivalent to Rational Exponents.
HOWTO: Given a square root radical expression, use the product rule to simplify it. Factor any perfect squares from the radicand. Write the radical expression as a product of radical expressions. Simplify.
So we're just going to write this-- let me write it over here. We can switch the order here because we just have a bunch of things being multiplied by each other. So I'll write the a squared over here. b to the fifth is not a perfect cube by itself, but it can be expressed as the product of a perfect cube and another thing. b to the fifth is the exact same thing as b to the third power times b.

In general, how would you explain to someone how to write a simplified equivalent expression when given something that looks like the examples above? Notes By looking at four different examples, students should observe that the base does not change, whether it is a whole number, fraction, variable, etc., but the exponent is what represents the number of times the base is multiplied by itself.
