Answer 1

The expanded form of a number is a way of writing a number as the sum of its individual digit values, with each digit multiplied by its place value.

(A) 7·1000+8·100+3· 1/100 is the expanded form of a number.
(B) 4·100+9·100+3· 1/10 +4· 1/10 is the expanded form of a number.
(C) 71·10+4·1+6· 1/100 +5· 1/1000 is the expanded form of a number.
(D) 5·1000+5·100+5·1+5·1/100 is the expanded form of a number.
(E) 3·1000+8·1000+9·1/1000 is the expanded form of a number.
(F) 9·1000+3·101+5· 1/10 is not the expanded form of a number as the second term 3·101 is not a valid place value.

Therefore, options A, B, C, D, and E are the correct answers.
