  • @dwboy the negative 3 is squared causing it to cancel out the negatives and making it into positve that is why it works

  • thank you so much! im gonna ace my final thanks to you

  • thank you, i have exam retake coming up in a couple of days and you are a great help

  • @dwboy u cant hav the log of any negative #

  • I don't understand why x = -3 is an extraneous answer when log_3((-3)^2) is valid and causes LHS = RHS.

  • This really helped me! thank you random internet person who's probably a teacher!(:
