Here are the essential concepts you must grasp in order to answer the question correctly.
Rationalizing the Numerator
Rationalizing the numerator involves eliminating any square roots or irrational numbers from the numerator of a fraction. This is typically achieved by multiplying both the numerator and the denominator by a suitable expression that will create a perfect square in the numerator, allowing for simplification.

Simplifying Fractions
Simplifying fractions means reducing them to their simplest form, where the numerator and denominator have no common factors other than 1. This process often involves factoring both the numerator and denominator and canceling out any common factors.

Square Roots and Their Properties
Square roots are mathematical expressions that represent a number which, when multiplied by itself, gives the original number. Understanding the properties of square roots, such as √(a*b) = √a * √b and √(a/b) = √a / √b, is essential for manipulating expressions involving square roots effectively.
