| Algebra.Com's Answer #595647 by Boreal(15235)     You can put this solution on YOUR website! The first one is fine.\r \n" ); document.write( "\n" ); document.write( "I'd probably simplify the second as I went along. Note: 729^2=531441, but no square. It has just been done.The first step you made has to have the 81^2 done before it is put in the parentheses. You would have 9 log3(9*81^2). It is easier to put the exponent in front so you have 9 log3(9) +2log3(81). The first is 18 (9*2) and the second is (4*2)=8\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "9log3 (9)=9*2=18\r \n" ); document.write( "\n" ); document.write( "log3 (81^2)=2log 3(81) OR log3(6561) \n" ); document.write( "log3(6561)=8\r \n" ); document.write( "\n" ); document.write( "18+8=26 \n" ); document.write( " \n" ); document.write( " |
