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
