1. Problem Description

The problem is to solve the inequality (12)x<8(\frac{1}{2})^x < 8 for xx.

2. Solution Steps

First, rewrite the inequality in terms of powers of

2. $(\frac{1}{2})^x < 8$

We can rewrite 12\frac{1}{2} as 212^{-1} and 88 as 232^3. So, we have:
(21)x<23(2^{-1})^x < 2^3
Using the power of a power rule, we get:
2x<232^{-x} < 2^3
Since the base is greater than 1, we can compare the exponents while preserving the inequality:
x<3-x < 3
Multiply both sides by -

1. Remember to reverse the inequality sign when multiplying by a negative number:

x>3x > -3

3. Final Answer

x>3x > -3
