Question

Explain how to convert 2.7 × 104 from scientific notation to standard form, then give the answer in standard form.

Answer 1

When converting scientific notation to standard form you will move the decimal the number of times that is shown in the exponent which in this case is 4. So , you move the decimal to the right since it is a positive 4 then that would give you the number 27,000 which is in standard form.

Answer 2

The exponent positive 4 means we move the decimal four spaces to the right.

The 2.7 becomes 27,000 after doing so

`2.7 * 10^4 = 27,000`

If the exponent was negative, then we would move the decimal point to the left.
