    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

    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)
