Calculators are not allowed starting in 2008. For the school year there will be two dates on which the contest may be taken: AMC 12A on , , , and AMC 12B on , , . Solution 2 (Algebra) Complete the square of the left side by rewriting the radical to be From there it is evident for the square root of the left to be equal to the right, must be equal to zero. Also, we know that the equivalency of square root values only holds true for nonnegative values of , making the correct answer. ~AnkitAmc.Solution 2 (Powers of 9) We need to first convert into a regular base- number: Now, consider how the last digit of changes with changes of the power of Note that if is odd, then On the other hand, if is even, then. Therefore, we have Note that for the odd case, may simplify the process further, as given by Solution 1. ~Wilhelm Z.
