(1331)−(2/3)=
A1/11
B-1/121
C1/121
D-1/11
Answer:
C. 1/121
Read Explanation:
First, convert the negative exponent: $(1331)^{-(2/3)} = 1 / (1331)^{2/3}$.
Next, apply the fractional exponent by taking the cube root first: $1 / (\sqrt[3]{1331})^2$.
Substitute the value of the cube root: $1 / (11)^2$.
Finally, calculate the square: $1 / (11 × 11) = 1 / 121$.
