    Applications of Radical Equations and Functions

    I have stuck on the question below for 3 days so I really need someone to help me out.

    (The number of hours needed to cook a turkey that weights x lb can be approximated by

    t(x)=0.90x^(3/5)

    where t(x) is the time in hours and x is the weight of the turkey in pounds.Find the weight of a turkey that cooked for 4hr. )

    I tried it out but it looks weird to me.

    After step (2)

    x[sup:22ncdd4y]3/5[/sup:22ncdd4y] = 40/9

    x = (40/9)[sup:22ncdd4y]5/3[/sup:22ncdd4y]

    Now use calculator......
