How do you write 0.007 in standard form?

Answer 1

To convert a number to standard form:

1. write out the number starting with the first non-zero digit and continue until the last non-zero digit;
2. put the decimal point after the first digit (if there is only 1 digit, the decimal point does not need to be written);
3. count how many digits the decimal point needs to move to get back to where it was originally (if there was no decimal point as the number was a whole number it was "hiding" after the ones-digit, the last digit);
4. if the decimal point needs to move left make this count negative;
5. write ×10 to the power of this count after the number written in step 2.

For 0.007 this gives 7 × 10⁻³

Answer 2

To write 0.007 in standard form, you would move the decimal point three places to the right to make it a whole number. This would result in 7 x 10^-3, where the negative exponent indicates the number of places the decimal point was moved. Therefore, 0.007 in standard form is 7 x 10^-3.

Answer 3

It is 7*10--3.

Answer 4

7x103

Answer 5

7 x 10^3
