Final answer:
To rewrite a radical expression as an expression with a rational exponent, follow these steps: identify the index of the radical as the denominator of the rational exponent and rewrite the radicand as the base raised to the power of the rational exponent.
Step-by-step explanation:
To rewrite a radical expression as an expression with a rational exponent, we can use the inverse relationship between radicals and rational exponents. Here are the steps:
Identify the index of the radical as the denominator of the rational exponent.
Rewrite the radicand as the base raised to the power of the rational exponent.
For example, if we have √x, we can rewrite it as x1/2. And if we have 3√x, we can rewrite it as x1/3.
