Algebra.Com's Answer #125530 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The questions are rewrite the following expression using one or more properties of logarithims and evaluate without a calculator. \n" ); document.write( "1. log 5 (25^2/5)= Log5(25^2) - log5(5) = 2log(5^2) - 1 = 4-1 = 3 \n" ); document.write( "---------------------------- \n" ); document.write( "Note the \"-\" to the right of the 5 has no meaning is nothing \n" ); document.write( "follows it. \n" ); document.write( "------------------------------ \n" ); document.write( "============================================================ \n" ); document.write( "2. log5 (125) + log5 (5) = 2 + 1 = 3 \n" ); document.write( "================================================================= \n" ); document.write( "I was able to figure out a portion of the problem but then got lost. Please check and help me with the rest. log5 (125x5)= log5 625 ( this is where I got lost) \n" ); document.write( "-- \n" ); document.write( "Correct answer: log5(125*5) = log5(125) + log5(5) = 3+1 = 4 \n" ); document.write( "============================================================ \n" ); document.write( "3. log9 3 - log9 243= \n" ); document.write( "Correct answer: \n" ); document.write( "[log3/log9] - [log243]/log9] \n" ); document.write( "Using base 3 to would get: \n" ); document.write( "[1/2] - [5/2] = -2 \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
