Here are the essential concepts you must grasp in order to answer the question correctly.
Exponents
Exponents represent repeated multiplication of a number by itself. For example, in the expression 15^4, the base 15 is multiplied by itself four times (15 × 15 × 15 × 15). Understanding how to manipulate exponents is crucial for simplifying expressions, especially when dividing or multiplying terms with the same base.

Properties of Exponents
The properties of exponents, such as the quotient rule, state that when dividing two exponential expressions with the same base, you subtract the exponents. For instance, a^m / a^n = a^(m-n). This property allows for simplification of expressions like 15^4 / 5^4 by rewriting them in a more manageable form.

Mental Math Techniques
Mental math techniques involve strategies to perform calculations in your head without the use of paper or a calculator. Techniques such as breaking down numbers into simpler components or using known squares and cubes can help simplify complex calculations, making it easier to compute values like 15^4 / 5^4 quickly and accurately.
