Question

This question is a log function which I need help on

Answer 1

Hi there! The answer is e^5

$5 + 7 ln(x) = 40$
Subtract 5.

$7 ln(x) = 35$
Divide by 7.

$ln(x) = 5$

Keep in mind.
$ln(x) = log_{e}(x)$

Therefore, we get the following.
$ln(x) = 5 \: \: gives \\ x = {e}^{5}$

Hence, the answer is e^5.
