Algebra.Com's Answer #13647 by venugopalramana(3286) You can put this solution on YOUR website! ln ((square root x) divided by (y square root z)). \n" ); document.write( "PUT BRACKETS PROPERLY \n" ); document.write( "LN{SQ.RT(X)/(Y*SQ.RT(Z))}IT MEANS SQ.RT.X IS DIVIDED BY BOTH Y AND SQ.RT.Z. \n" ); document.write( "SO WE GET -O.5 LN Z AND NOT +0.5 LN Z \n" ); document.write( "WHERE AS IF IT HAD BEEN \n" ); document.write( "LN{SQ.RT(X)/(Y)*(SQ.RT(Z)},IT COULD BE TAKEN AS \n" ); document.write( "LN{(SQ.RT(X))*(SQ.RT(Z))/(Y),WHEN YOUR ANSWER IS OK. SO PROPER USE OF BRACKETS IS VERY IMPORTANT.HOPE YOU UNDERSTOOD. \n" ); document.write( "i got .5lnx-lny+.5lnz, but the last part is supposed to be -.5lnz. what did i do wrong? thanks \n" ); document.write( " |
