Rewrite this number using scientific notation 425,000

what will this be could you explain it?
Thank you

In scientific notation the number left of the decimal must be 1, 2 ..... 9

nothing smaller, nothing bigger
so it is
4.25 times something
4.25*10^1 = 42.5
4.25*10^2 = 425
4.25*10^3 = 4,250
4.25*10^4 = 42,500
4.25*10^5 = 425,000

the answers choices is

425*10^5
4.25*10^5
4.25*10^4

I'll think it's A
