the radius of the Sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. Express each of these numbers in an alternate form In scientific notation

Respuesta :

Explanation;

Writing scientific notation :

  • Move the decimal to the left side until single digit of number remains before the decimal.
  • Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
  • For Example: [tex]2894.55=2.89455\times 10^{3}[/tex]

Radius of the sun = 696,000.0 kilometer

[tex]1 km=10^3 m[/tex]

Radius of the sun can also be written as = [tex]6.96\times 10^{5} km=6.96\times 10^{5}\times 10^3 m=6.96\times 10^{8} meter[/tex]

Size of bacterial cell = [tex]1.9\times 10^{-4}[/tex] millimeter

[tex]1 mm=1\times 10^{-3} m[/tex]

Size of bacterial cell can also be written as = [tex]1.9\times 10^{-4}\times 10^{-3} m=1.9\times 10^{-7} meter[/tex]
