    Is this equation correct?

    y = e^3


    e^3 = y
    e = 3SQRT(y)
    (3SQRT(y))^2 = e^2
    3^2y = e^2
    9y = e^2
    y = e^2/9

    Thanks

    No, it fails at the first line.

    e=cbrt(y)

    I do not know exactly what you want but I think this is what you want

    e^3=y

    e=\sqrt[3]{y}

    e=y^{\frac{1}{3}}

    e^2=y^{\frac{2}{3}}

    Hi bobbyboy1111

    That's sure one super weird problem. How can you solve y = e^3 ?

    IMO, y= e^3 itself can be considered as solution...

    Does the post I originally wrote make sense? If so, I would try that and see what happens

    No, it doesn't. You can take a look post #3 by Amer as reference

    And do not use that kind of color since it's hard to read
