Lessons for F.LE.A.4
Evaluating logarithms, common and naturalAsking what power of the base gives the number, for bases and numbers that work out whole.Lesson
Definition of a logarithmRewriting a logarithm statement as the power statement it stands for, and back again.Lesson
Solving logarithmic equationsAn answer must be dropped if it makes any logarithm in the original equation take a value that is not positive.Lesson
Graphs of logarithmic functionsThe exponential's mirror image across y = x.Lesson
Laws of logarithmsThe logarithm of a product is the sum of the logarithms, because powers with the same base add.Lesson
Semi-log plots: straightening exponential data with logarithmsTaking the logarithm of the output turns exponential data into a line, and logs of both variables turn a power law into one.Lesson
Solving exponential equations by matching basesIf both sides are powers of the same base, then the two exponents must be equal.Lesson
Solving by taking a logarithm of both sidesApplying a logarithm to both sides brings an unknown exponent down where it can be solved for.Lesson
