I am afraid I do not completely understand what you want. This calculator does not have a Computer Algebra System or CAS. So the results of all calculations will be displayed as decimal numbers, and that includes the square and other roots that are irrational numbers (square root of 2, 3, 5 7, etc.)

SOURCE: How do you convert decimal complex numbers in TI-84 (OS 2.53) to fractions?
I answered a similar question not long ago and here is what I wrote:
Not quite true for OS 2.56 MP for the TINspire with Ti84 keyboard. To
convert a complex decimal value, that you just calculated, into a
fraction use the command Math [1:>Frac] and it will convert the value
to complex fractions
See below.
I suggest you upgrade the OS to version 2.55 MP.
