Identidades de exponentes
(Mathemática | Álgebra | Exponentes)

Potencias

xa xb = x(a + b)

xa ya = (xy)a

(xa)b = x(ab)

x(a/b) = bth(root)(xa) = ( bth (root)(x) )a

x(-a) = 1 / xa

x(a - b) = xa / xb

Logaritmos

y = logb(x) si y solamente si x=by

logb(1) = 0

logb(b) = 1

logb(x*y) = logb(x) + logb(y)

logb(x/y) = logb(x) - logb(y)

logb(xn) = n logb(x)

logb(x) = logb(c) * logc(x) = logc(x) / logc(b)
