Question

NECESITO AYUDA CON LOS LOGARITMOS

Answer 1

...

a)

$= log_{3}(15) \\ = log_{3}(5 \times 3) \\ = log_{3}(5) + log_{3}(3) \\ = log_{3}(5) + 1$

b)

$= ln(4) \\ = ln({3}^{2}) \\= 2ln(2)$

c)

$= log_{2}( \sqrt{2} ) \\ = log_{2}( {2}^{ \frac{1}{2} } ) \\ = \frac{1}{2} log_{2}(2) \\ = \frac{1}{2}$

d)

$= log(20) \\ = log(10 \times 2) \\ = log(10) + log(2) \\ = log(2) + 1$

e)

$= log_{2}(9) \\ = log_{2}( {3}^{2} ) \\ = 2 log_{2}(3)$
