Solve for x 9e^x=107

$9 e^{x} = 107$

Step 1

Divide each term in $9 e^{x} = 107$ by $9$ and simplify.

Divide each term in $9 e^{x} = 107$ by $9$ .

$\frac{9 e^{x}}{9} = \frac{107}{9}$

Simplify the left side.

Cancel the common factor of $9$ .

Cancel the common factor.

$\frac{9 e^{x}}{9} = \frac{107}{9}$

Divide $e^{x}$ by $1$ .

$e^{x} = \frac{107}{9}$

Step 2

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

$\ln (e^{x}) = \ln (\frac{107}{9})$

Step 3

Expand the left side.

Expand $\ln (e^{x})$ by moving $x$ outside the logarithm.

$x \ln (e) = \ln (\frac{107}{9})$

The natural logarithm of $e$ is $1$ .

$x \cdot 1 = \ln (\frac{107}{9})$

Multiply $x$ by $1$ .

$x = \ln (\frac{107}{9})$

Step 4

The result can be shown in multiple forms.

Exact Form:

$x = \ln (\frac{107}{9})$

Decimal Form:

$x = 2.47560425 \dots$
