Exponents and Expressions Evaluation

This video tutorial covers how to evaluate algebraic expressions with exponents using whole numbers, decimals, and fractions. It provides examples for each type of number and emphasizes the importance of following the order of operations. The video also suggests simplifying expressions before substituting values to make calculations easier. Key concepts include the power of a power rule and the use of BEDMAS (Brackets, Exponents, Division/Multiplication, Addition/Subtraction) in solving expressions.
