Here are the essential concepts you must grasp in order to answer the question correctly.
Exponents and Powers
Exponents represent repeated multiplication of a base number. For example, 20^2 means 20 multiplied by itself, which equals 400. Understanding how to manipulate exponents, such as dividing or multiplying them, is crucial for simplifying expressions involving powers.

Order of Operations
The order of operations is a set of rules that dictates the sequence in which calculations should be performed to ensure consistent results. The common acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) helps remember this order, which is essential for correctly evaluating expressions like the one given.

Fractional Exponents
Fractional exponents indicate roots as well as powers. For instance, an exponent of 1/2 represents the square root, while 3/2 indicates the square root followed by cubing. Recognizing how to interpret and calculate with fractional exponents is important for simplifying complex expressions involving division and multiplication of powers.
