To rewrite an expression in radical form, we use the property that \(a^{m/n} = \sqrt[n]{a^m}\). This means that the exponent's denominator becomes the index of the radical, and the numerator remains the power of the base inside the radical.
Step 1: Rewrite in Radical Form
To rewrite the expression \(2^{7/9}\) in radical form, we apply the property of exponents that states \(a^{m/n} = \sqrt[n]{a^m}\). Here, \(a = 2\), \(m = 7\), and \(n = 9\).
Step 2: Apply the Property
Using the property, we can express \(2^{7/9}\) as:
\[
2^{7/9} = \sqrt[9]{2^7}
\]
Final Answer
Thus, the radical form of the expression is:
\[
\boxed{2^{7/9} = \sqrt[9]{2^7}}
\]
