Step 1.1

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $1$ .

$\frac{lim_{x \to 1} n^{x} - lim_{x \to 1} 1}{m^{x} - 1}$

Step 1.2

Move the limit into the exponent.

$\frac{n^{lim_{x \to 1} x} - lim_{x \to 1} 1}{m^{x} - 1}$

Step 1.3

Evaluate the limit of $1$ which is constant as $x$ approaches $1$ .

$\frac{n^{lim_{x \to 1} x} - 1 \cdot 1}{m^{x} - 1}$

Step 2

Evaluate the limit of $x$ by plugging in $1$ for $x$ .

$\frac{n^{1} - 1 \cdot 1}{m^{x} - 1}$
