Question 845794
If the equation is {{{5^(2x+7)=9}}}, then...


{{{5^(2x+7)=9}}}


{{{2x+7=log(5,(9))}}}


{{{2x=log(5,(9))-7}}}


{{{x=(log(5,(9))-7)/2}}}



=========================================================================


OR...If the equation is {{{5^(2x)+7=9}}}, then...


{{{5^(2x)+7=9}}}


{{{5^(2x)=9-7}}}


{{{5^(2x)=2}}}


{{{2x=log(5,(2))}}}


{{{2x=log(5,(2))}}}


{{{x=(log(5,(2)))/2}}}
