I created this product as a result of my own difficulty in finding a good set of practice problems on this topic to give my algebra students.
Three worksheets (30 problems) are included in this download.
Students will use conjugates to rationalize denominators containing radicals.
Worksheet A is easiest as it contains ten questions that do not require reducing or simplifying of radicals. There will be some negative numbers in the denominators so students can learn to deal with them.
Worksheet B consists of ten questions that are a mix of problems that do and do not require reducing. No simplifying of radicals is involved in this set of problems.
Worksheet C is the most challenging set of ten questions as they involve both reducing and simplifying of radicals.
