Answer 1

To determine which expression simplifies to leave a positive exponent, let's simplify each option one by one:

1. **−2(−3)²**
- This simplifies to \(-2 \cdot 9 = -18\), which does not involve exponents in the final result.

2. **3⁻³ + 3⁻⁴**
- This can be rewritten as \(\frac{1}{3³} + \frac{1}{3⁴}\).
- Finding a common denominator: \(\frac{3}{3⁴} + \frac{1}{3⁴} = \frac{3 + 1}{3⁴} = \frac{4}{3⁴} = 4 \cdot 3⁻⁴\).
- This expression still has a negative exponent (specifically \(3^{-4}\)).

3. **32(3⁻⁵)**
- This simplifies to \(9 \cdot 3^{-5} = 9/3^5\), which can be expressed as \(9/243\) but also still has a negative exponent.

4. **3⁻(11/3) − 3⁻(7)**
- Here, we can rewrite this as \(3^{-11/3} - 3^{-7}\).
- Informally, we can factor out a common term if we consider them on a common base; however, both terms retain negative exponents after simplification.

The only expression that results in a simplified version that does not retain any negative exponents requires reviewing this question's specific requirements.

None of the provided expressions end up resulting with a positive exponent when fully simplified.

Please double-check the specific context or any possible miscommunication about the task, as, based on standard exponent rules, none of the options yield a purely positive exponent in the final simplified form provided above.
