Answer 2

Answer:

Step-by-step explanation:

1)

8^-11÷2^-11

Using, a^m÷b^m = (a/b)^m

(8/11)^-11

Using, a^-m= 1/a^m

(8/11)^-11= (11/8)^11

2)

(3^-2)^-3÷3^-3

Using (a^m)^n = a^mn

(3^-2)^-3= 3^6

3^6÷3^-3

Using, a^m÷a^n= a^m-n

3^6-3

=> 3^3

3)

81^-5÷(3^2)^-5

Using, (a^m)^n= a^mn

81^-5÷3^-10

Using, a^-m= 1/a^m

81^-5= (1/81)^5

3^-10= (1/3)^10

(1/81)^5÷  (1/3)^10

here are your answer.
