LOGARÍTMOS

Question 1

Nomeie os termos de Log x A = B

Answer 1

B = Log de A na base x
A = Logaritmando
X = base

Question 2

Defina Log x A = B

Answer 2

X^B = A

Question 3

Log b 1 = ?
Log b b = ?
Log b B^n = ?
B^(log b A) = ?

Answer 3

Log b 1 = 0 (pois B^0 = 1)

Log b b = 1 (pois B^1 = B)

Log b B^n = n (pois b^n = b^n)

B^(log b A) = A (regra do sobe e desce)

Question 4

Log XY = ?
Log X/Y = ?
Log X^y = ?
Mudança de base

Answer 4

Log XY = Log X + Log Y

Log X/Y = Log X - Log Y

Log X^y = Y * Log X

Mudança de base: Log y X = Log z X / Log z Y
