Kirkland rolls four dice and forms a 4-digit number.
Part A
Which expressions do not represent the number in expanded

o 7,000 + 900 + 60 + 8
o 7,000 + 900 + 80 + 6
o (1,000 x 7) + (100 x 9) + (10 x 6) + (8 x 1)
o (7 x 1,000) + (9 x 100) + (6 x 10) + (1 x 8)
o (7 x 100) + (9 x 100) + (6 x 10) + (1 x 8)
