Algebra.Com's Answer #307672 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! log 4 (x ^2 -3) + log 4 10=1 \n" ); document.write( "log 4 10(x ^2 -3) =1 \n" ); document.write( "10(x ^2 -3) = 4^1 \n" ); document.write( "10x^2 -30 = 4 \n" ); document.write( "10x^2 = 34 \n" ); document.write( "x^2 = 3.4 \n" ); document.write( "x = sqrt(3.4) \n" ); document.write( "x = {-1.84, 1.84} \n" ); document.write( "throw out the negative solution (extraneous) leaving: \n" ); document.write( "x = 1.84\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
