    Is there a simple way to solve this or do you need approximation?

    I need to solve ((-3/2)*b^(2/3))+b=-5/16
    for b.


    I know the answer should be around .199, but is there an easy way to solve it? I tried to factor out a b, but got a different answer that did not make sense. Anyone know how to solve it? Thanks.

    Hello,

    By letting x=b^{1/3}, you can use these completely insane formulae : Cubic function - Wikipedia, the free encyclopedia
