Answer/Solution

0

Steps/Work

The sum of the digits is 7+8+9+9=33.
Thus 3 is a factor of 7899, so 3 is a factor of z.
Then 3^3 = 9 is a factor of z^2.
Then the remainder when z^2 is divided by 9 is 0.
The answer is A.

Step by Step Solution

In order to solve problem, you must evaluate n2 * (n0 / 3^n1 / n2 - ((n2 - n1) * 1000 * 100 + (n2 - n1) * 1000 * 10 + n1 * 100 + 100 - n1)).

n0 =7899
n1 =2
n2 =9
