Question

Write the equation in logarithmic form. (1/3)^3=1/27

Answer 1

Answer:

$\log_{\frac{1}{3}} (\frac{1}{27})=3$

Step-by-step explanation:

The given equation is

$(\frac{1}{3})^3=\frac{1}{27}$

We need to write the equation in logarithmic form.

Taking log on both sides.

$\log (\frac{1}{3})^3=\log (\frac{1}{27})$

Using the property of logarithm we get

$3\log (\frac{1}{3})=\log (\frac{1}{27})$           $[\because \log a^b=b\log a]$

Divide both sides by $\log (\frac{1}{3})$.

$3=\dfrac{\log (\frac{1}{27})}{\log (\frac{1}{3})}$

Using the property of logarithm we get

$3=\log_{\frac{1}{3}} (\frac{1}{27})$          $[\because \log_x y =\dfrac{\log_ay}{\log_ax}]$

Therefore, the logarithmic form of given equation is $\log_{\frac{1}{3}} (\frac{1}{27})=3$.
