Final answer:
To write the function (-6)² = 81 in standard form, we expand the square to get x² = 36.
Step-by-step explanation:
To write the function (-6)² = 81 in standard form, we need to expand the square. (-6)² means (-6) multiplied by itself. So, (-6)² is equal to (-6)(-6), which is 36. Therefore, the standard form of the function is x² = 36.
