## thomaster 2 years ago I need to rewrite a formula

1. thomaster

$$\huge q=\left(\frac{25}{25+8.8*10}\right)^3~=\LARGE 0.0108$$ Now i need to calculate what's 10 in this one for another formula without the 3th powe. $$\LARGE 0.0108\huge =\left(\frac{25}{25+8.8*V_{org}}\right)$$ I know the answer is 260 by solving for x but how to rewrite this formula to get V org before the equal sign. I was thinking of this: $$\huge V_{org}=\frac{\left(\Huge\frac{25}{25+8.8}\right)}{0.0108}$$ But it gives me the wrong answer. What did i do wrong?

$\LARGE 0.0108\huge =\left(\frac{25}{25+8.8*V_{org}}\right)$ $\LARGE 25+8.8*V_{org}\huge =\left(\frac{25}{0.0108}\right)$ $\LARGE 25+8.8*V_{org}\huge =\left(\frac{25}{0.0108}\right)$ $\LARGE 8.8*V_{org}\huge =\left(\frac{25}{0.0108}\right)-25$ $\LARGE V_{org}\huge =dfrac{\left(\frac{25}{0.0108}\right)-25}{8.8}$

neglect last one sorry

4. AravindG

$\LARGE V_{org}\huge =\dfrac{\left(\frac{25}{0.0108}\right)-25}{8.8}$
