First to figure this out.
3^2 = 9
3^4 = 81
3^6 = 729
Then multiplied together
=531,441
Now to figure out each value to see which one is equivalent to 531,411.
a) obviously not
b) no that equals 59,049
c) This would be the answer, 3 to the 12 power equals 531,441 ( used a calculator to check my answer.)

Therefore, your answer is C.
Have a great night.
