Here are the essential concepts you must grasp in order to answer the question correctly.
Radical Expressions
Radical expressions involve roots, such as square roots, cube roots, and higher-order roots. The notation ⁹√ indicates the ninth root of a number. Understanding how to manipulate these expressions is crucial for simplification, especially when dealing with exponents and variables.

Exponents and Roots
Exponents represent repeated multiplication, while roots are the inverse operation. For example, the expression 5³ means 5 multiplied by itself three times, and the ninth root of a number asks what number, when raised to the ninth power, equals that number. This relationship is essential for simplifying radical expressions.
