Here are the essential concepts you must grasp in order to answer the question correctly.
Radicals
Radicals are expressions that involve roots, such as square roots, cube roots, etc. In this context, the notation √n represents the square root of n, while n√m denotes the nth root of m. Understanding how to manipulate and simplify radical expressions is essential for solving problems involving multiplication and simplification of radicals.

Multiplication of Radicals
When multiplying radicals, the product of the radicands can be taken under a single radical sign. For example, √a ⋅ √b = √(a*b). This property allows for the simplification of expressions by combining the radicands before simplifying further. It is crucial to apply this rule correctly to achieve the simplest form of the expression.

Simplifying Radicals
Simplifying radicals involves reducing the expression to its simplest form, which often includes factoring out perfect squares or cubes from the radicand. For instance, √(a*b) can be simplified if a or b is a perfect square. This process is important for presenting the final answer in a clear and concise manner, especially in algebraic expressions.
