Algebra.Com's Answer #749962 by Alex.33(110)![]() ![]() You can put this solution on YOUR website! Assume lg refers to the logarithm with a base of 10. I'll show the fastest way I can think up, somewhat similar to where you are at. \n" ); document.write( "lg(3^x-2^(4-x))=2+(1/3)lg8-(1/4)xlg16 \n" ); document.write( "lg(3^x-2^(4-x))=lg(100)+(1/3)lg(2^3)-(1/4)xlg(2^4) \n" ); document.write( "lg(3^x-2^(4-x))=lg(100)+lg2-xlg2 \n" ); document.write( "lg(3^x-2^(4-x))=lg(200)-lg(2^x) \n" ); document.write( "lg(3^x-2^(4-x))=lg(200/(2^x)) \n" ); document.write( "3^x-(2^4/2^x)=200/(2^x) \n" ); document.write( "6^x-16=200 \n" ); document.write( "6^x=216 \n" ); document.write( "x=3\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
