You cannot manipulate radicals with this calculator. All radical results will be displayed as (approximate) decimal numbers.

SOURCE: i have a ti 83 plus calculator and when i type in


Your TI83 calculator is a powerful machine but it does not do symbolic algebra. Results are always displayed in decimal form
(Did you notice that it does not have a %key.)

Some new (not very expensive) calculators can do that : Casio FX-300es, Casio FX-115es,Casio FX-991ms or es. These type of calculators are known as NATURAL DISPLAY, or WRITE VIEW (from Sharp).

Hope it helps.

SOURCE: How do you simplify a radical to get another

If you have a TiNspire CAS, you can check the Settings and make sure that the calculation mode is set to Exact.
In HOME press 5:Settings and Status > 2: Settings > 1:General >Tab>Tab>Tab>Tab Calculation Mode :Exact.
Unlike the TINspire CAS, the TINspire does not have an exact calculation mode. It just has Auto and Approximate. From the looks of it, you may not be able to use radicals, let alone simplify them. But I may be wrong.
