Chapter 7: Q. 56 (page 604)

Evaluate the limits in Exercises 55–60. Use the theorems in this section to justify each step of your work.
$\lim_{k \to \infty} (1 + \frac{1}{k}) (2 - \frac{1}{k})$

Short Answer

Expert verified

$\lim_{k \to \infty} (1 + \frac{1}{k}) (2 - \frac{1}{k}) = 2$

Step by step solution

Step 1. Given information

$\lim_{k \to \infty} (1 + \frac{1}{k}) (2 - \frac{1}{k})$

Step 2. Calculate the limit

$\lim_{k \to \infty} (1 + \frac{1}{k}) (2 - \frac{1}{k}) = (1 + \frac{1}{\infty}) (2 - \frac{1}{\infty})$

$\lim_{k \to \infty} (1 + \frac{1}{k}) (2 - \frac{1}{k}) = 1 \times 2$

$\lim_{k \to \infty} (1 + \frac{1}{k}) (2 - \frac{1}{k}) = 2$
