Answer:
4/9
Explanation:
1) since we know that; when a fraction is raised to a negative power, we take reciprocal of the fraction and raise both the numerator and the denominator to a positive power,
(27/8)^-⅔
that's how we write it then
2) we take the reciprocal and multiply with positive power respectively
(8/27)⅔
that is by expanding
8^⅔/27^⅔
enter it in your calculator and you should get
4/9
hope that helps!
