How do you think the given expressions with a rational exponent were written as radicals? What processes have you observed?
• To rewrite a radical using a fractional exponent, the power to which the radicand is raised becomes the numerator and the root becomes the denominator. Any radical in the form can be written using a fractional exponent in the form
What necessary understanding is needed to simplify the given expression?
• All you need to simplify most expressions is basic arithmetic -- addition, subtraction, multiplication, and division -- and the order of operations
What are the bases for arriving at your conclusion?
• My conclusion is based on when the variable has been raised to the power of exponent
