Algebra.Com's Answer #747044 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Both tutor @mathlover1 and tutor @josgarithmetic pointed out that if log(A) = log(B), then it should be true that A=B. They both overlooked that fact that A must be equal to B IF A SOLUTION EXISTS. \n" ); document.write( "Tutor @maththerapy is right; there is no solution. That is because when you set A=B in this equation, you get x = -9/4. Then the equation says \n" ); document.write( "log(-21/4) = log(-21/4) \n" ); document.write( "But logs of negative numbers do not exist. \n" ); document.write( "So, as tutor @maththerapy says: NO SOLUTION \n" ); document.write( " \n" ); document.write( " |
