Algebra.Com's Answer #170792 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! My problem is: solve log(x^2+3)=log(x+6) There is no log base, so do I set the ( )= ( )? Can this be worked on a graphing calc. TI-83 plus? If so, how do I enter it. I know where the log button is and y=button. Thank you.
