Question

What is the scientific notation for 0.0043

Answer 1

4.3 x 10^-3

Step-by-step explanation

The answer would be 4.3 x 10^-3, or 10 to the negative third power, because scientific notation rules require the number to be more or equal to 1, but less than 10. 4.3 would fit in the criteria since it is more than 1 but over 10. If you move the decimal three places to the right, it would fit to make 4.3. Since you are in the decimals place, it would have to be a negative power. Therefore, due to the fact that you moved it three times, it would be 10^-3. Finally, you would be left with 4.3 x 10^-3.

Answer 2

4.3 x 10^-3

Explanation:

For scientific notation, the number has to be between 0.1 repeated and 9.9 repeated. The ^ means power. In this case 10 t the negative 3 power. It is 10 t the negative 3 power because we moved the decimal place to the right 3 places in order to fit the form for scientific notation for 4.3
