A. 1\9
B. 9
C. 3
D. -9​

Answer 1

Answer:

Since it is given in ques that 27 to the power -2/3 and 27 can be written as 3 to the power 3 as cube of 3 gives 27

27 = 3×3×3

also it is given in power -2/3.......so when we write 27 in in the form of power 3 and 3 cancels out

3×-2/3 = -2

Now,

we get 3 to the power -2 which can also be written in 1/3 to the power 2 which gives the value 1/9

1/3×3 = 1/9

hence, the correct answer is 1/9
