Question 3(Multiple Choice Worth 3 points) (07.04) 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 3x+1 = log15 Step 2: (x + 1)log 3 = log15 Step 3: x + 1 = log 15 over log 3 Step 4: x+1 = 2.708050 over 1.098612 Step 5: x + 1 = 1.418858 Step 6: x = 0.418858 Step 1 Step 2 Step 3 Step 4
