How do you write 3.5 × 10^3 in standard form?
Nutka1998 [239]

Answer:

3500

Step-by-step explanation:

Given the following question:

3.5\times10^3

To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.

Since the exponent is three, we know that the decimal point is going to move to the right THREE times.

3.5\times10^3
3.5\times10^3=3.5.0.0.
3.5.0.0.=3500
=3500

Your answer in standard form is "3500."

Hope this helps.
