1. **State the problem:** Solve the inequality $3^x + 1 > 1$ and the equation $3^x = 1$.
2. **Solve the inequality $3^x + 1 > 1$: **
Subtract 1 from both sides:
$$3^x + 1 - 1 > 1 - 1$$
$$3^x > 0$$
Since $3^x$ is an exponential function with base 3 (which is positive and greater than 1), it is always positive for all real $x$. Therefore, the inequality holds for all real numbers.
3. **Solve the equation $3^x = 1$: **
Recall that any number to the power 0 is 1:
$$3^0 = 1$$
Therefore, the solution is:
$$x = 0$$
**Final answers:**
- Inequality $3^x + 1 > 1$ is true for all real $x$.
- Equation $3^x = 1$ has solution $x = 0$.
