Algebra.Com's Answer #416883 by lwsshak3(11628) ![]() You can put this solution on YOUR website! log[10](3m-5)+log[10](m)=log[10](2) \n" ); document.write( "log[(3m-5)(m)]=log2 \n" ); document.write( "(3m-5)(m)=2 \n" ); document.write( "3m^2-5m-2=0 \n" ); document.write( "(3m+1)(m-2)=0 \n" ); document.write( "3m+1=0 \n" ); document.write( "m=-1/3 (reject, m>0 \n" ); document.write( "m-2=0 \n" ); document.write( "m=2 \n" ); document.write( "Check: \n" ); document.write( "plug in 2 to the original equation \n" ); document.write( "log[10](3m-5)+log[10](m)=log[10](2) \n" ); document.write( "log[10](6-5)+log[10](2)=log[10](2) \n" ); document.write( "log[10](1)+log[10](2)=log[10](2) \n" ); document.write( "0+log[10](2)=log[10](2) \n" ); document.write( "log[10](2)=log[10](2) \n" ); document.write( "m=2 is the correct ans \n" ); document.write( " \n" ); document.write( " |
