Question 1170142

{{{log(25, 2) + log(25, (25 - 4x) )= 0.5}}}


{{{log(25, 2 (25 - 4x) )= 0.5}}}......convert to base {{{10}}}


{{{log( 2 (25 - 4x) )/log(25)= 1/2}}}


{{{log( 2 (25 - 4x) )= (1/2)log(25)}}}


{{{log( 2 (25 - 4x) )= log(25^(1/2))}}}


{{{log( 2 (25 - 4x) )= log(sqrt(25))}}}


{{{log( 2 (25 - 4x) )= log(5)}}}..........if log same, then


{{{ 2 (25 - 4x) = 5}}}


{{{  25 - 4x = 5/2}}}


{{{  25 - 5/2 =4x }}}


{{{  45/2 =4x }}}


{{{ x= (45/2)/4 }}}


{{{ x= 45/8 }}}


{{{ x=5.625}}}
