Question

Considerando Log2=0,3 e Log3=0,5 determine o valor:
a)Log5
b)Log72
c)Log³√3
d)Log648

Answer 1

a) ㏒(2 * 3) = ㏒(2) + ㏒(3) = 0.3 +0.5 = 0.8

b) ㏒(2³ * 3²) = 3㏒(2) +2㏒(3) = 0.9 +1 = 1.9

c) $\mathsf{log(3^{ \frac{1}{3} }) = \frac{log(3)}{3}}$ = 0.5/3 ≈ 0.167

d) ㏒(2³ * 3⁴) = 3㏒(2) +4㏒(3) = 0.9 +2 = 2.9
