f(x) = (6/7)2/3 Solve with any differentiation rule from 1 to 4

1. The given function is \( f(x) = \frac{6}{7} \frac{2}{3} \). First, we simplify:
f(x) = \frac{12}{21} = \frac{4}{7} \text{ (constant)}

2. The derivative of a constant is zero for any differentiation rule (1 to 4). Therefore:

f'(x) = 0

So, the final answer is zero.
