Directions: Using the digits 1 to 9, at most one time each, create a sequence that is in numerical order and cannot be simplified anymore.
Hint
How are radicals simplified to get the index? What does that index represent?
Answer
More than one answer. One possible is 3sqr(7), 8sqr(2), 5sqr(6)
The reasoning and approach would be of real interest and a comparison amongst student answers.

Not sure I agree with the word ‘sequence’ here. Doesn’t sequence usually imply that there is a pattern to get the next term?
Not necessarily, when it says sequence it is referring to the “numerical order” considering that is a pattern.
