Question

Sabendo que log a=2 e log b=-1, calcule o valor de:

Answer 1

a)

$Log_{b}\, a = \frac{Log \, a}{Log \, b} = \frac{2}{-1} = -2$

b)

$Log_{a}\, b = \frac{-1}{2}$

c)

$\frac{2 Log \, b}{Log\, a} = \frac{2 * -1}{2} = -1$

d)

$Log\,a + Log\,b = 2 - 1 = 1$

e)

$Log\,a -Log\,b = 2 -(-1) = 3$

f)

$\frac{Log\,a}{\frac{Log\, b}{2}} = \frac{2 * 2}{-1} = -4$
