Question: User: x = 1/x^2
1. **State the problem:** Solve the equation $$x = \frac{1}{x^2}$$ for $x$. 2. **Rewrite the equation:** Multiply both sides by $$x^2$$ to eliminate the denominator: $$x \cdot x^2 = \frac{1}{x^2} \cdot x^2$$ which simplifies to: $$x^3 = 1$$ 3. **Solve for $x$:** To solve $$x^3 = 1$$, take the cube root of both sides: $$x = \sqrt[3]{1}$$ 4. **Evaluate the cube root:** The cube root of 1 is 1, so: $$x = 1$$ 5. **Check for extraneous solutions:** Substitute $x=1$ back into the original equation: $$1 = \frac{1}{1^2} = 1$$ which is true. 6. **Consider domain restrictions:** Since the original equation has $x^2$ in the denominator, $x \neq 0$ to avoid division by zero. 7. **Final answer:** The solution is: $$x = 1$$
