In a mathematical reasoning exercise, students are presented with a puzzle involving the ages of Rosie's and Tia's sisters, who are the same age. The clue provided is that the current age of each sister is a square number, and in two years, their ages will be cube numbers. This problem requires students to identify a number that is both a perfect square and, when increased by two, becomes a perfect cube. The solution to this problem reveals that the sisters are 25 years old, as 25 is the square of 5, and 27, which is two years older than 25, is the cube of 3. This exercise combines knowledge of multiplication and division with the properties of square and cube numbers, challenging students to apply their understanding of these mathematical concepts to solve the problem.

The task encourages students to think critically and use logical reasoning to find the intersection of square and cube numbers within the context of real-life scenarios, such as determining ages. By exploring the relationship between square and cube numbers, students deepen their comprehension of number properties and enhance their problem-solving skills. This type of question is typical in mathematics education, aimed at fostering a deeper understanding of number theory and its practical applications. The exercise also serves as a reinforcement of the concepts of multiplication, division, and the significance of square and cube numbers in mathematics.
