Spotting and Correcting Common Fallacies in Logarithm Algebra
Identify and correct common errors, such as confusing log(x + y) with log(x) + log(y) or log(x)/log(y) with log(x - y).

Apply change of base, construct formal index law proofs, evaluate parametric logarithmic terms, and eliminate common algebraic fallacies.
[Understand and use the laws of logarithms: log a x+log a y=log a (xy); log a x–log a y=log a x y ; klog a x =log a xk (including, for example, k =−1 and k =− )]
