$2^{x} = 37$

Step 1

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

$\ln (2^{x}) = \ln (37)$

Step 2

Expand $\ln (2^{x})$ by moving $x$ outside the logarithm.

$x \ln (2) = \ln (37)$

Step 3

Divide each term in $x \ln (2) = \ln (37)$ by $\ln (2)$ and simplify.

Step 3.2.1.1

Cancel the common factor.

$\frac{x \ln (2)}{\ln (2)} = \frac{\ln (37)}{\ln (2)}$

Step 3.2.1.2

Divide $x$ by $1$ .

$x = \frac{\ln (37)}{\ln (2)}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$x = \frac{\ln (37)}{\ln (2)}$
