$\frac{lim_{x \to 0} e^{5 x} - 1 - 5 x}{x^{2}}$

Step 1

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $0$ .

$\frac{lim_{x \to 0} e^{5 x} - lim_{x \to 0} 1 - lim_{x \to 0} 5 x}{x^{2}}$

Step 2

Move the limit into the exponent.

$\frac{e^{lim_{x \to 0} 5 x} - lim_{x \to 0} 1 - lim_{x \to 0} 5 x}{x^{2}}$

Step 3

Move the term $5$ outside of the limit because it is constant with respect to $x$ .

$\frac{e^{5 lim_{x \to 0} x} - lim_{x \to 0} 1 - lim_{x \to 0} 5 x}{x^{2}}$

Step 4

Evaluate the limit of $1$ which is constant as $x$ approaches $0$ .

$\frac{e^{5 lim_{x \to 0} x} - 1 \cdot 1 - lim_{x \to 0} 5 x}{x^{2}}$

Step 5

Move the term $5$ outside of the limit because it is constant with respect to $x$ .

$\frac{e^{5 lim_{x \to 0} x} - 1 \cdot 1 - 5 lim_{x \to 0} x}{x^{2}}$

Step 6

Evaluate the limits by plugging in $0$ for all occurrences of $x$ .
