Logarithms Algebra 2 Ashley solved the exponential equation 3x+1 = 15 and her work is shown below. What is the first step she did incorrectly? Step 1: log 3^(x+1) = log15 Step 2: (x + 1)log 3 = log15 Step 3: x + 1 = log 15/log 3 Step 4: x+1 = 2.708050/1.098612 Step 5: x + 1 = 1.418858 Step 6: x = 0.418858

    Well, obviously \[2.708050/1.098612 \neq1.418858\](you can see that without even checking it in a calculator, right?) I don't see anything up to that point that is wrong (although the use of "log" when actually using "ln" is a bit confusing....).
