Question

If f (x) =  \[\log_{x_2}\]write the value of f' (x). 

Advertisements

Solution

\[f(x) = \log_{x^2} x^3 \]
\[ = \frac{\log x^3}{\log x^2} (\text{ Change of base property })\]
\[ = \frac{3 \log x}{2 \log x}\]
\[ = \frac{3}{2}\]
\[f'\left( x \right) = 0 (\text{ Since } \frac{3}{2} \text{ is a constant })\]
