How do I find the element of a(base 1),(base 2)?

You shouldn't put the word "base" there. You should put "row 1" 
instead of "base 1" and "column 2" instead of "base 2". The 
first number in a%5Br%2Cc%5D, the r, is the row number 
going from top to bottom, and the second number c is the 
column number going from left to right.  You can remember which
is which by remembring that a%5Br%2Cc%5D looks like the word 
"arc".  

          C C C 
          O O O 
          L L L
          U U U
          M M M
          N N N
          # # # 
          1 2 3 
          ¯ ¯ ¯ 
ROW #1 ® 1 2 3 
ROW #2 ® 4 5 6 
ROW #3 ® 7 8 9

The 1 is in ROW #1 and COLUMN #1, so 1 is the element a%5B1%2C1%5D
The 2 is in ROW #1 and COLUMN #2, so 2 is the element a%5B1%2C2%5D
The 3 is in ROW #1 and COLUMN #3, so 3 is the element a%5B1%2C3%5D
The 4 is in ROW #2 and COLUMN #1, so 4 is the element a%5B2%2C1%5D
The 5 is in ROW #2 and COLUMN #2, so 5 is the element a%5B2%2C2%5D
The 6 is in ROW #2 and COLUMN #3, so 6 is the element a%5B2%2C3%5D
The 7 is in ROW #3 and COLUMN #1, so 7 is the element a%5B3%2C1%5D
The 8 is in ROW #3 and COLUMN #2, so 8 is the element a%5B3%2C2%5D
The 9 is in ROW #3 and COLUMN #3, so 9 is the element a%5B3%2C3%5D

Your answer is the red one.
