The table shows the values of different measurements in the metric system.
Lunna [17]

A micrometer has a power of 10^{-6}

A millimeter has a power of x 10^{-3}

A nanometer  has a power of 10^{-12}

A picometer  has a power of 10^{-12}

We are to write the numbers in standard form.

Standard form is a way of writing simplifying numbers and expressing numbers to a power of 10.

For example, to express 1000  in standard form, count the number of digits after the first number. There are 3 zeros. 3 would be the power of the number. So, 1000 in standard form is 1 x 10³

To express a decimal in standard form, count the numbers of zeros and the first non-zero digit  The negative of the number would be the power.

For example, 0.001 is standard form is 1 x 10^{-3}

A micrometer has 6 digits after the decimal point , it power would be x 10^{-6}

A millimeter has 3 digits after the decimal point, its power would be x 10^{-3}

A nanometer has 9 digits after the decimal point, its power would be x 10^{-12}

A picometer has 12 digits after the decimal point, its power would be x 10^{-12}
