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).

The expressions can be rewritten using the rule of exponent:


x^{(a)/(b)}=\sqrt[b]{x^a}

QUESTION A


\sqrt[3]{12}

In rational exponent form, we have the expression to be:


\Rightarrow12^{(1)/(3)}

QUESTION B


\sqrt[4]{10^7}

In rational exponent form, the expression will be:


\Rightarrow10^{(7)/(4)}

QUESTION C


14^{(2)/(5)}

In radical form, the expression will be:


\Rightarrow\sqrt[5]{14^2}

QUESTION D


\sqrt[8]{15^3}

In rational exponent form, the expression will be:


\Rightarrow15^{(3)/(8)}

QUESTION E


21^{(9)/(4)}

In radical form, the expression will be:


\Rightarrow\sqrt[4]{21^9}
