Answer:
B
Explanation:
A negative exponent in the numerator is a positive exponent in the denominator.
(4/3)^-3 in the numerator is (4/3)^3 in the denominator.
A zero exponent makes the expression equal 1.
((3/4)^5)^0 = (3/4)^0 = 1
A power raised to a power is the product of the powers.
((3/4)^3)^4 = (3/4)^12
Put everything together, and you get B.
