    Rearranging an equation help please

    Hi,

    I want to rearrange this equation so that I can solve for D...

    X = A * B * C^2 * SQRT(D * E/F)

    I worked on it for a couple hours but I am way over my head with this.

    Thanks fo your help

    The trick is to isolate D

    You can do this by using inverse operations.

     X = ABC^2\sqrt{\frac{DE}{F}}

    firstly divide ABC^2 from both sides.

     \frac{X}{ABC^2} = \sqrt{\frac{DE}{F}}

    Now square both sides to remove the square root

     \left(\frac{X}{ABC^2}\right)^2 = \frac{DE}{F}

    Do you think you can have a go from here? All you have to do is multiply through by F and then divide through by E.

    Thanks!

    D = (F((X/ABC^2)^2))/E ?
