Chapter 7: Q. 21 (page 639)

Simplify the quotients in Exercises 21–28 without using a calculator.
$\frac{8!}{10!}$

Short Answer

Expert verified

The value is $\frac{1}{90} .$

Step by step solution

Step 1. Given information.

The given expression is $\frac{8!}{10!}$ .

Step 2. Value of the expression.

Now,

$n! = n (n - 1)! \frac{8!}{10!} = \frac{8!}{10 \times 9 \times 8!} = \frac{1}{90}$

Express each of the repeating decimals in Exercises 71–78 as a geometric series and as the quotient of two integers reduced to lowest terms.

$1.272727 . . .$

Let 0 < p < 1. Evaluate the limit $\lim_{k \to \infty} \frac{1 / k \ln k}{1 / k^{p}}$

Explain why we cannot use a p-series with 0 < p < 1 in a limit comparison test to verify the divergence of the series $\sum_{k = 2}^{\infty} \frac{1}{k \log k}$

Consider the series

Fill in the blanks and select the correct word:

$I f \lim_{k \to \infty} \frac{a_{k}}{b_{k}} = \infty and \sum_{k = 1}^{\infty}_____diverges t he n \sum_{k = 1}^{\infty}_____(converges / diverges) .$

Use either the divergence test or the integral test to determine whether the series in Given Exercises converge or diverge. Explain why the series meets the hypotheses of the test you select.

$\sum_{k = 1}^{\infty} \frac{\tan^{- 1} k}{1 + k^{2}}$

Explain why the integral test may be used to analyze the given series and then use the test to determine whether the series converges or diverges.

$\sum_{k = 2}^{\infty} \frac{1}{k (\ln k)^{2}}$
