Question

How do you convert `4.74 x 10^3` into standard form?

Answer 1

`4.74xx10^3 = 4740` (in standard form)

Explanation:

`10^3 = 1000`
so
`4.74xx10^3 = 4.74xx1000 = 4740`

Perhaps a simplified way to think of it is
if given a number in scientific notation
`color(white)("XXXX")` `"a.bcd"xx10^k`
`k` (if positive) is the number of places the decimal point needs to be moved to the right to get the standard notation value.
(If `k` is negative the decimal point needs to move to the left).
