How do you write 3624 in expanded form using exponents?

Answer 1

3624 in expanded form is 3000 + 600 +20 +4 translate the expanded form in exponents: 3000= 3* 10 to the power of the 3 600= 6* 10 to the power of 2 20 = 2* 10 to the power of 1 4= 4* 10 to the power of 0

Answer 2

1. Put the decimal point after the first non-zero digit.
2. Count how many digits the decimal point needs to move to get back to where it was (if there was no decimal point it was hiding after the number)
3. If the decimal point needs to move to the left to get back to where it was, make the count in step 2 negative
4. multiply the number in step 1 by 10 to the power of the number that is the result of steps 2 and 3.

The number written in step 1 can be rounded if necessary to a number of significant figures (after the count in step 2 has been made)

That's how I write it in expanded form, this is it being done for 23800167:

1. 2.3800267
2. need to move decimal point 7 digits to get it back to the right hand end
3. moving right, so leave positive (+7)
4. 2.3800267 x 107

So 23800167 = 2.3800167x107

To 3 sig fig, 2.3800267 → 2.38

⇒ 23800167 ≈ 2.38 x 107
