Today we move beyond adding, subtracting, multiplying and dividing as we begin working with powers. In 4.1 we'll discuss exponentiation and practice the order of operations with powers. In 4.2 you'll practice applying powers. This material is covered on pages 169-178 in the Engaging Algebra textbook.
4.1 An Introduction to Exponentiation
After working with these videos, you will know the difference between an exponent and a power and you'll be able to use the order of operations to simplify expressions that have powers.
4.2 Applying Powers
After your work in 4.2 you'll know how to check the answer for a quadratic equation, find the value of a discriminant and evaluate a quadratic function.
