Algebra.Com's Answer #25386 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Okay, from \n" ); document.write( "log(5)625 + log(9)(x-3) = 6 \n" ); document.write( "let us evaluate the left hand log first... \n" ); document.write( "we ask, \"What exponent must we raise 5 to to get to 625?\" Well, 4. So we have \n" ); document.write( "4 + log(9)(x-3) = 6 \n" ); document.write( "log(9)(x-3) = 2 \n" ); document.write( "Now convert this to an exponential form... \n" ); document.write( "9^2 = x - 3 \n" ); document.write( "81 = x - 3 \n" ); document.write( "x = 84 \n" ); document.write( " |
