Algebra.Com's Answer #486698 by rothauserc(4718) You can put this solution on YOUR website! 2log(x-1) = 2 + log100 \n" ); document.write( "note that log 100 = log (base 10) 100 and 10^2 = 100 so log 100 = 2 \n" ); document.write( "2log(x-1) = 2 + 2 \n" ); document.write( "2log(x-1) = 4 \n" ); document.write( "divide both sides of = by 2 \n" ); document.write( "log(x-1) = 2 \n" ); document.write( "note that log base is 10 and by definition of logarithm \n" ); document.write( "x-1 = 10^2 \n" ); document.write( "x = 100 +1 \n" ); document.write( "x = 101 \n" ); document.write( " \n" ); document.write( " |
