    Simplifying radical expressions with my Ti-89

    Hello,

    I'm wondering if there is a way I can change the way my answer is being given on my TI-89 while simplifying radical expressions with variables all representing positive numbers.

    For example

    √320x^10

    is being answered as 4*5^1/3 * x^10/3

    and I would like for it to be shown as
    4x^3√5x

    or
    √32x^5 to be shown as 2x√4x^2 instead of (2x)^5/3

    Is this possible? It would be really helpful! Thank you by the way I'm using a Ti-89 Titanium I also have a Ti-83 Plus.

    What do you mean? Those 2 expressions do not equal each other;
    CHECK yourself: assign some value to x
