Si log_b a = x → a = b^x; a>0; b>0; b≠1

log₁₀a = loga

log_ea = lna

log_bb = 1

log_b1 = 0

log_b(x^r) = rlog_bx

log_b(b^x) = x

b^log_bx = x

log_ab · log_bc · log_cd = log_ad

log_ax = log_bx / log_ba

log_bx / log_ax = log_ba

log_b(xy) = log_bx + log_by

log_b(x/y) = log_bx - log_by

colog_bx = log_b(1/x) = log_b(1) - log_bx = -log_bx =
