Answer: a) 3424 b) 2145 c) 10211

Explanation:

First, list out the powers of 5 starting from right to left. Stop when the next power of 5 is greater than 489. (Sorry if that was confusing)

----- ----- ----- -----

125 25 5 1

Then, divide 489 by the powers of 5 starting from the left.

489/125 = 3 r 114

3 would be your first number

Divide the remainder by the next number to the right.

114/25 = 4 r 14

So now, you have 34.

Repeat the process.

14/5 = 2 r 4

Now you have 342.

4/1 = 4

You get 3424.

Repeat these steps for b (with powers of 9) and c (with powers of 3).

Hope this helped! (Sorry, this whole explanation was really confusing)
