Dylan solved the exponential equation 3x+1 = 15 and his work is shown below. What is the first step he did incorrectly?
Step 1: log3x+1 = log15
Step 2: 3 log(x + 1) = log15
Step 3: log(x + 1) = log 15 over 3
Step 4: log(x + 1) = 0.3920304
Step 5: ln[log(x + 1)] = ln0.3920304
Step 6: x + 1 = −0.936415
Step 7: x = −1.936415
I know it's either step 2 or step 3. This is just all so confusing to me...
