Which logarithmic equation is equivalent to the exponential equation below?

aleksandr82 [10.1K]

Option B: $\ln 6=5 x$ is the correct answer.

Explanation:

The exponential equation is $e^{5 x}=6$

If $f(x)=g(x)$ , then $\ln (f(x))=\ln (g(x))$

Thus, the equation becomes

$\ln \left(e^{5 x}\right)=\ln (6)$

Applying log rule, $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$ and thus the equation becomes

$5 x \ln (e)=\ln (6)$

Since, we know that, $\ln (e)=1$ , using this we get,

$5 x=\ln (6)$

Hence, the logarithmic equation which is equivalent to the exponential equation $e^{5 x}=6$ is $\ln 6=5 x$

Thus, Option B is the correct answer.

Linda purchases 4/5 of a pound of apples for $5.00. What is the cost per pound of apples?

bonufazy [111]

Answer:

$6.25 per pound

Step-by-step explanation:

We can set up a simple ratio to solve this.

If 4/5 pounds = $5, then 1 pound = x

We can write two ratios and equate them:

$\frac{\frac{4}{5}}{5}=\frac{1}{x}\\\frac{4}{5}x=5\\x=\frac{5}{\frac{4}{5}}\\x=5*\frac{5}{4}\\x=\frac{25}{4}\\x=6.25$

So 1 pound of apple cost $6.25
