I am having a bit of trouble with the way I've rearranged this, as it does not fit my model. Just want to see if anyone gets the same rearrangement as myself.

THANKS!

I'm sorry, but I could not figure out how to write it correctly, especially on this. Everytime I uploaded it, it kept changing my spacing, etc.

Hi marysmith!

You can write you equation like this:

[TEX]L_m = \left[ \frac {3 \varepsilon S} {\rho g \kappa} \right]^{1/2} Q^{1/2}[/TEX]

$\displaystyle L_m = \left[ \frac {3 \varepsilon S} {\rho g \kappa} \right]^{1/2} Q^{1/2}$

I'm not sure I understand your question correctly.

It seems you want to isolate Q.

If that is the case, you can do:

$\displaystyle L_m = \left[ \frac {3 \varepsilon S} {\rho g \kappa} \right]^{1/2} Q^{1/2}$

$\displaystyle Q^{1/2} = \left[ \frac {\rho g \kappa} {3 \varepsilon S} \right]^{1/2} L_m$

$\displaystyle Q = \left[ \frac {\rho g \kappa} {3 \varepsilon S} \right] L_m^2$
