Question

Which of the following values are equal to $\log 125$?

• A. $100\log 1.25$
• B. $5\log 3$
• C. $3\log 25$
• D. $3\log 5$
• E. $\log 25\log 5$

Answer 1

The correct option is D $3\log 5$

$\log 125=\log \left(5^3\right)$

$\Rightarrow 3\log 5$

$\log 125=\log \left(\frac{1000}{8}\right)$

$\log \left({10}^3\right)-\log \left(2^3\right)$

$\Rightarrow 3-3\log \left(2\right)$
