Answer:
The standard form of [tex]3.15*10^{-7}[/tex] is 0.000000315.
The radius of the bacterium is 0.000000315 meters.
Answer:
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.
