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
Step 1
Step 2
Step 3

Vocaloid · Answer

should be step 2 actually

log3x+1 does not equal 3log(x+1)

Vocaloid · Answer

3log(x+1)  would be equal to log((x+1)^3)
