Question

Can someone help me with this question?

Answer 1

25 / 81(25 by 81) is your answer.

Answer 2

25/81.

Explanation:

(27/8)^-4/3

= 8^4/3 / 27^4/3

= (∛8)^4 / (∛27)^4

= 16 / 81

(64/125)^-2/3

= (125)^2/3 / (64)^2/3

= (∛125)^2 / (∛64)^2

= 5^2 / 4^2

= 25/16

So the answer is

16/81 * 25/16

= 25/81.
