Given that $a^xb^{2x}c^{3x}=2$ , where $a$ , $b$ , and $c$ are positive real numbers, then $x=$

\log_{10}\left(\dfrac2{a+2b+3c}\right)

\dfrac{\log_{10}2}{\log_{10}(a+2b+3c)}

\dfrac2{\log_{10}(a+2b+3c)}

\dfrac2{a+2b+3c}

\log_{10}\left(\dfrac2{ab^2c^3}\right)

\dfrac{\log_{10}2}{\log_{10}(ab^2c^3)}

\dfrac2{\log_{10}(ab^2c^3)}

\dfrac2{ab^2c^3}
