The answer to this question is supposed to be 3; I can do half of the question, but then I get stuck.

Numerator: (6^4 + 4^6)^0

Denominator: 3^-1

From that I got:

Numerator: 2

Denominator: 3^-1

Then I did the flip thing to get rid of the negative exponent:

Numerator: 2

Denominator: 1/3^2

Then I simplified:

Numerator: 2

Denominator: 1/9

How can I simplify this further?
