Assignment 1

Calculate:

$\log_5(25)$

$\log_3(81)$

$\log_2(0.125)$

Solution

We use the definition of a logarithm:

$\log_5(25)=y\Longleftrightarrow 5^y=25\Rightarrow y=2$

$\log_3(81)=y\Longleftrightarrow 3^y=81=3^4\Rightarrow y=4$

$\log_2(0.125)=y\Longleftrightarrow 2^y=0.125=\displaystyle\frac{1}{8}=2^{-3}\Rightarrow y=-3$
