Answer 1

(10,000,000)(2,000,000)(400,000)(30,000)

Answer 2

`1 \cdot 10^7 +2 \cdot 10^6+ 4 \cdot 10^5+ 3 \cdot 10^4`

Explanation:

write 12,430,000 in expanded form using exponents

First we write the expanded form of each digit

1 is in ten millions place , 1 times 10,000,000

2 is in millions place , 2 times 1,000,000

4 is in hundred thousands place , 4 times 100,000

3 is in ten thousands place , 3 times 10,000

Now we write it in expanded form

`1 \cdot 10,000,000 +2 \cdot 1,000,000 + 4 \cdot 100,000+ 3 \cdot 10,000`

`1 \cdot 10^7 +2 \cdot 10^6+ 4 \cdot 10^5+ 3 \cdot 10^4`
