D. ใ3()
Step-by-step explanation:
From the logarithm exponent property, we can say the expression given is equivalent to:
ใ3(x^4) - ใ3(y^20)
Using the logarithm subtraction property, we can say that the expression is also equivalent to:
ใ3()
This is the same as option D.
Note: The formatting is a bit weird cuz I'm not good at using it.
