  • how would you do 1-0.75^x > 0.625 ???

  • negative number inside the log* not negative answer

  • I'm a bit confused here. You say the answer is between -2 and 5/2. So, I plug in a number between 0 and 0.5 into the original equation log[x(2x-1)] and come out with a negative answer. However, you cannot have an answer like log(-2) or any other negative number in your log. So, why are the values from 0 < x < 0.5 defined as true?

  • thanx for the video.

    it helps me a lot !!!
