Determine which powers have the value of 81.

Choices: 

1^81, 3^4, 6^4, 9^2, 27^3

Evaluate each values separately to determine the correct answer.

1^81 = 1 (1 multiplied to itself will result to 1, no matter how many times you repeat it.)

3^4 = 81

(3)(3)(3)(3) = 81

6^4 = 1296

(6)(6)(6)(6) = 1296

27^3 = 19,683

(27)(27)(27) = 19,683

Therefore the correct answer is 3^4
