Isn't this just taking whatever you grab out of the radical and dividing the inside by it twice?

[@jakobhansson1341]

No 3x7=21 so its not prime??? Or???? I'm confused now......???

[@jakobhansson1341]

I can't make it work with the square root of 21? It's just 3x7 so no pair of numbers?? Or am I missing something??? Or is 21 prime maybe???!!!!! Thats probably it???!!!

[@helenhart4368]

3 and 7 are each prime. Your answer would have to be: (square root of 3)(square root of 7) Or it might make more sense to leave it as square root of 21. I guess it depends on what you’re trying to do with it.

[@Lexiecutioner]

The square root of 21 can’t be simplified any further, so the answer would just be "square root of 21"
