Answer:

81

Step-by-step explanation:

27 =(3)^3 .

169 =13^2 ;

343 = 7^3.

81 = 9^2

In the above, all 3,13,7 are prime numbers also they can not be expressed in any other form except as shown above when expressed using exponents.

But 81 is a number which can be expressed as 3^4 as well as 9^2 also while expressing like that we get 9 , a composite number.
