Type the correct answer in each box. use numerals instead of words.
in scientific notation, the radius of each bacterium in a petri dish is 3.15 x 10-7 meter. the radius of the bacterium written as a decimal numb
in standard form is
meters.

The standard form of is 0.000000315.

The radius of the bacterium is 0.000000315 meters.

0.000000315 meters

Explanation:

The radius of each bacterium in a petri dish is 3.15 x 10^-7 meter. To convert this number in scientific notation into decimal number in standard form, see 3.15 x 10^-7 as its equivalent division,  that is:

3.15 x 10^-7 = 3.15/10^7 = 3.15/10000000

To perform this division you have to move the decimal point in 3.15 seven steps (the number of zeros in 10^7) to the left and complete the empty spaces with zeros. Place the decimal point there. In this case, that makes six zeros between the 3 and the decimal point. Finally, add a zero to the left of the decimal point.
