How do reply to her question that she did good job. Here is her answer. The question I chose to solve is 4^x - 6 = 4 I started off by adding 6 on both sides giving me, 4^x=10. In order for me to get x alone, I set the equation to log(4)4^x=log(4)10. Log(4) cancels out the coefficient leaving me with x=log(4)10. To get the answer, I used the change base rule and it gave me log10/log4. I solved the problem and it gave me my answer of 1.6610
