Final answer:
To rewrite an expression in rational exponent notation, convert it to a base raised to a fractional exponent. To rewrite an expression in radical notation, express it as a root.
Step-by-step explanation:
To rewrite an expression in rational exponent notation, we need to convert it to a base raised to a fractional exponent. For example, if we have √a, we can rewrite it as a^(1/2). Similarly, to rewrite an expression in radical notation, we need to express it as a root. For instance, a^(3/4) can be written as the fourth root of a cubed, ∛a^3.
Let's consider an example: if we have (9^2/3), we can rewrite it as the cube root of 9 squared, ∛9^2. Similarly, if we have the square root of 16, we can rewrite it as 16^(1/2).
