Final answer:
The equivalent expression to 4f² / (1/4f) is found by multiplying the numerator and denominator by the reciprocal of the denominator, resulting in 16f³, which is option 1).
Step-by-step explanation:
The student has asked which expression is equivalent to 4f² / (1/4f). To find the equivalent expression, we can simplify by multiplying both the numerator and the denominator by 4f, which is the reciprocal of the denominator.
Here's the step-by-step simplification:
- Multiply the numerator and denominator by 4f: (4f² × 4f) / ((1/4f) × 4f).
- Simplify the denominator: 4f × (1/4f) = 1, so the denominator is now 1.
- Multiply out the numerator: 4f² × 4f = 16f³.
- Since the denominator is 1, we are left with the numerator only: 16f³.
Therefore, the expression equivalent to 4f² / (1/4f) is 16f³, which corresponds to option 1).
