$\ln ({(e)}^{7.3}) = \ln (32.7)$

Step 1

Rewrite the equation.

$\ln (32.7) = 7.3$

Step 2

Rewrite the equation in exponential form using the definition of a logarithm. If $x$ and $b$ are positive real numbers and $b \neq 1$ , then $y = l o g (b) (x)$ is equivalent to $b^{y} = x$ .

$e^{7.3} = 32.7$

Step 3

The left side $1480.29992758$ does not equal to the right side $32.7$ , which means that the given statement is false.

False
