Re-arranging an equation with a square root

Question

I need to re-arrange the following equation to make $d$ the subject [i.e., solve for $d$]:

$$a = \sqrt{\frac{d}{be}}.$$

The square root part is really confusing me, any help would be much appreciated.

Ok. Squaring both sides you obtain $$a^{2} = \frac{d}{be} \Longrightarrow d = (be) \times a^{2}$$

	Thanks, is it possible to re-arrange it without the brackets though? – Dennis Henry Nov 18 '10 at 21:41
	@Dennis: Yes, i used brackets only for the sake of convenience – anonymous Nov 18 '10 at 21:42
	Thanks, so what has happened to the 'a' part? – Dennis Henry Nov 18 '10 at 21:44
	@Dennis: According to your notation $a=M^{2}b^{2}e^{2}$ – anonymous Nov 18 '10 at 21:48
	Sorry, I'm not sure if I'm managed to explain it correctly, please can you see the below image of the equation? – Dennis Henry Nov 18 '10 at 21:53
