Chapter 10: Q51. (page 528)

Solve the inequality $16^{n} < 8^{n + 1}$ . Check your solution.

Short Answer

Expert verified

The solution for the inequality is $n < 3$ .

Step by step solution

Step 1. Write down the given inequality.

The given inequality is $16^{n} < 8^{n + 1}$ .

Step 2. Simplify the inequality.

The given inequality $16^{n} < 8^{n + 1}$ is solved as:

$\begin{array}{l} 16^{n} < 8^{n + 1} .... (Given) \\ {(2^{4})}^{n} < {(2^{3})}^{n + 1} \\ {(2)}^{4 n} < {(2)}^{3 n + 3} \\ 4 n < 3 n + 3 \\ n < 3 \end{array}$

Step 3. Verify the result for obtained value.

Plugging $n = 2$ in given inequality and verify the result.

$\begin{array}{l} 16^{n} < 8^{n + 1} .... (Given) \\ 16^{(2)} < 8^{(2) + 1} \\ 16^{2} < 8^{3} \\ 256 < 512.... (True) \end{array}$

Hence the solution is verified for $n = 2$ .

Step 4. Conclusion.

The solution for the given inequality is $n < 3$ .
