Final answer:
Trisha's simplified expression of the given expression is incorrect. The correct answer is False.
Step-by-step explanation:
Trisha's simplification of the expression (2m¹⁴n⁴³m²n¹²)² is incorrect. To simplify the expression, we need to multiply the exponents inside the parentheses by 2. This gives us (2²m²⁸n⁸⁶m⁴n²⁴). So, Trisha's simplified expression should be 4m²⁸n⁸⁶m⁴n²⁴, which is different from the given answer, 4m²⁴n¹⁶⁹. Therefore, the correct answer is B. False.
