Algebra.Com's Answer #153764 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 4log(1-5x)= 2 \n" ); document.write( "-------------------- \n" ); document.write( "A \"log\" is an exponent \n" ); document.write( "--- \n" ); document.write( "In your problem 4 times the \"exponent\" = 2 \n" ); document.write( "So the \"exponent\" must be 2/3 or 1/2. \n" ); document.write( "---------------------- \n" ); document.write( "So log(1-5x) = 1/2 \n" ); document.write( "----- \n" ); document.write( "You might ask: Exponent of what? \n" ); document.write( "Since your problem does not show the base, \n" ); document.write( "the word \"log\" means the base is 10. \n" ); document.write( "----------- \n" ); document.write( "So 1-5x = 10^(1/2) \n" ); document.write( "---- \n" ); document.write( "Solve for \"x\" \n" ); document.write( "5x = 1-sqrt(10) \n" ); document.write( "x = -0.4325... \n" ); document.write( "=============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
