Log rule confusion during : Log = 1 + Log

Log5(x2) = 1 + Log5(6)

  1. Uses rule a=logb(ba) to get log5(x2) = log5(30)
  2. x2= 30
  3. x = square of 30


There is nothing online about “1 + logarithms” and when there is they expotentate. Why is this rule used? Everything is easy except for when it is explained as “log5(51+log5(6))” which somehow equals 30
