(4)-(10^-(x/2))=1/3

i was thinking of taking logs of both sides or putting e^of.... in but i'm looking at it & just confusing myself over it

$\displaystyle 10^{-x/2}=\frac{11}{3}$

$\displaystyle \frac{-x}{2}=\log_{10} \left(\frac{11}{3}\right)$

$\displaystyle x=-2 \cdot \log_{10} \left(\frac{11}{3}\right)$ - Apr 13th 2012, 03:15 AMbobmarly12345Re: solve the following equation for x:
thank you thats great :)
