Question

If a1=a2=a3 then can i say a1=a2=a3=1 ?

Answer 1

Not necessarily. See below

Explanation:

We need other restriction in order to stablish that `a_i=1`

Because by the same reason we can stablish `a_i=0` or `a_i=sqrt3`

For example, the statement coud be "find the lowest positive integer value....". In this case `a_i=1` could be an answer. In other cases we can say only `a_1=a_2=a_3` and we can assume that all of them are 1 in order to know what happen in this particular case

Hope this helps
