Answer :
37 trillion can be written as 37 x 10^12. This means that there are 37 times 10 to the power of 12 cells in an average human body.
According to question:
a. 37 trillion can be written as 37 x 10^12. This means that there are 37 times 10 to the power of 12 cells in an average human body.
b. 300 billion can be written as 300 x 10^9. This means that there are 300 times 10 to the power of 9 stars in the Milky Way.
c. 23 millionths can be written as 23 x 10^-6. This means that the thickness of a sharp knife's tip is 23 times 10 to the power of negative 6 meters.
d. 4 nanometers can be written as 4 x 10^-9. This means that the wall of a certain cell in a plant is 4 times 10 to the power of negative 9 meters thick. Since a nanometer is one billionth of a meter, 4 nanometers is equivalent to 4 times 10 to the power of negative 9 meters.
