Question

5 ogarithmic equation in exponential form: log(5k + 4) = 8r

Answer 1

Given:

$\log (5k+4)=8r$

To find:

The exponential form of given equation.

Solution:

We have,

$\log (5k+4)=8r$

According to the property of the logarithm,

$\log_ax=y\Rightarrow x=a^y$

Using the above property of the logarithm, we get

$5k+4=10^{8r}$        

Therefore, the required equation in exponential form is $5k+4=10^{8r}$.
