# Math Help - Rearranging an equation help please

1. ## 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.

2. 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.

3. Thanks!

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