Grade 6 Expressions - 6.EE.A.1

We have worked with our core competency as far as exponents so far which states that an exponent is simply a multiple of the root value by how ever many times it is raised to a power. What if that power was fraction? How would you adjust your calculations based on that? When working with a fractional exponent, the denominator of that exponent serves as the degree of radical that it creates. The purpose of the numerator is the power of the term found inside that radical. In order to proficiently use this skill, you should be well versed on the concepts of roots and anatomy of them. Rational exponents lend themself well to many different uses of the quadratic equations. There are also many different financial applications of this type of math that allow us to make reliable forecast and thereby allowing business leaders to make sound decisions. Economists use this technique often to compute interest rates and create various types of financial products. It is often used to understand the concepts of depreciation and inflation. This can help you assess the stunted or diminishing progression of just about anything with a quantitative value. This series of lessons and worksheets will help you better understand the core fundamentals of working with and using rational exponents.

  • Homework 3 - We now add an operation that you must evaluate as well.
  • Homework 4 - This can be complicated if do not plan out the steps that you will take along the way.
  • Homework 5 - You will need to draw up the steps of your approach for this one too.



Practice Worksheets

This selection of sheets will help students better understand the sequence they should use to solve these problems.

  • Practice 1 - Write each expression as a radical in simplest form.
  • Practice 2 - You may leave improper fractions in the exponent.
  • Practice 3 - The focus here is end off with positive exponents.
  • Practice 4 - Do not forget that an operation is found within every expression.
