Here are the essential concepts you must grasp in order to answer the question correctly.
Exponent Rules
Understanding exponent rules is crucial for simplifying expressions involving powers. Key rules include the product of powers (a^m * a^n = a^(m+n)), the quotient of powers (a^m / a^n = a^(m-n)), and the power of a power (a^(m*n) = a^mn). These rules help in combining and simplifying terms effectively.

Negative Exponents
Negative exponents indicate the reciprocal of the base raised to the opposite positive exponent (a^-n = 1/a^n). In simplification, it's important to convert negative exponents to positive ones to adhere to the problem's requirement of expressing answers without negative exponents, which often involves rewriting the expression.

Simplifying Rational Expressions
Simplifying rational expressions involves reducing fractions to their simplest form by canceling common factors in the numerator and denominator. This process often requires applying exponent rules and ensuring that all variables are treated as positive real numbers, which affects how we handle the exponents in the expression.
