To convert exponential to radical expression and vice versa, we follow the pattern below:
[tex]ab^{\frac{x}{n}}=a\sqrt[n]{b^x}^{}[/tex]In the given term in the question, a = 5, b = x, n = 9, and x = 1. Let's plug these values into the radical form shown above.
The radical form of the given term is:
[tex]5\sqrt[9]{x}[/tex]
