What are some equivalents to 5 radical 3?

Answer 1

5 radical 3 is just a number.

So, asking this is the same as asking 'What are some equivalents to 3?' One could answer 2 * 3 / 2. But this reduces to 3.

The situation is the same for your question. One could offer some multiple of 5 radical 3 as an answer but, being a multiple, it would reduce to 5 radical 3.

radical 3 is approximately 1.732 but not exactly 1.732 so one cannot say, for instance, that 5 radical 3 = 5 (1.732) = 8.660. In fact, there is not way of expressing radical 3 with a finite number of decimal places. So no-one can write radical 3 = 1.732.... exactly.

5 radical 3 is the best one can do.
