# Math Help - solve the following equation for x:

1. ## solve the following equation for x:

(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

2. ## Re: solve the following equation for x:

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

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

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