log_a(m) = x ⟺ a^x = mlog_a(1) = 0log_a(a) = 1Laws of Logarithms
log_a(mn) = log_a(m) + log_a(n)log_a(m/n) = log_a(m) - log_a(n)log_a(m^n) = n·log_a(m)log_a(b) = log_c(b)/log_c(a)log_a(b) = 1/log_b(a)Logarithmic Inequalities
If a > 1 and log_a(x₁) > log_a(x₂), then x₁ > x₂If 0 < a < 1 and log_a(x₁) > log_a(x₂), then x₁ < x₂Applied Results and Problem Solving
