Kai correctly used the different laws of logarithms to rewrite log27 - log (3/5) - log 5 as one logarithm.

His work is shown here

Step one: Log27 - (log3 - log5) - log 5

Step two: log (3^3) - log 3 + log 5 - log 5

Step three: log (3^3) - log3

Step 4: 3 log3 - log 3

Step 5: 2 log 3

Step 6: log (3^2)

Step 7: log 9

In which step (s) did kai apply the difference law for logarithms

A - step 3

B - step 5

C - step 4

D - step 1
