This math topic focuses on variable substitution in algebraic functions involving fractional squared terms. It targets students at a basic level of algebra. Specifically, students are asked to substitute given values into equations featuring square terms in fractional formats and solve for the result. Each problem offers multiple-choice answers, reinforcing the students' understanding and application of algebraic principles, particularly fractional exponents in equations. The exercises are part of a broader unit on algebra basics, aimed at developing foundational skills in algebraic manipulations and problem-solving.
