D. γ3(
)
Step-by-step explanation:
From the logarithm exponent property, we can say the expression given is equivalent to:
γ3(x^4) - γ3(y^20)
Using the logarithm subtraction property, we can say that the expression is also equivalent to:
γ3(
)
This is the same as option D.
Note: The formatting is a bit weird cuz I'm not good at using it.
