Converting Standard Form Numbers Back Into Ordinary Numbers

Показать описание
In this video you will shown how to change a standard index form number into an ordinary number. First decide, if the number is large (positive power), or small (negative power). For large numbers move the decimal point to the right as you are multiplying by 10, and for small number move the decimal point to the left as you are dividing by 10. The power will tell you how many places to move the decimal point. Fill the gaps in with zero's.

So in the first example you need to convert 3.9 x 10^5 to an ordinary number. Do this by moving the decimal 5 place right. This gives 390,000. In example 3 you need to change 5.1 x 10^-6 into standard index form. Do this by moving the decimal point 6 places left.
This gives a final answer of 0.0000051.

Although, you shouldn't be taught to move the decimal point, this is the quickest and most efficient way of converting standard form number into normal number.
