Question

How many ways can 54,625 be written in expanded form

Answer 1

In the number 54, 625 from left to right:

5 represents 5,
2 represents 20
6 represents 600
4 represents 4000
5 represents 50,000


so 

54,625=50,000+4,000+600+20+5=5*10,000+4*1000+6*100+2*10+5


another way we can write this number is $5.10^4+4.10^3+6.10^2+2.10+5$


Answer:
i) 5*10,000+4*1000+6*100+2*10+5
ii) $5.10^4+4.10^3+6.10^2+2.10+5$

2 ways, which are essentially the same thing.
