x is an integer greater than 1

Anindita Dey

We can simplify A a little bit. We can write A as 3^x * 3. Now that 3^x is a positive number we can divide A and B by 3^x.

That leads us to: 3 ?? (4/3)^x.

Now because 4/3 is greater than 1, it's clear that if x's value increase the value of B will also increase. So at one point it will be greater than 3. Thus the answer is D.
