Question

In scientific notation, the radius of the Sun is

× 10
kilometers.

In expanded notation, each bacterial cell is
millimeters wide.

Answer 1

Step-by-step explanation:

696,000 km = 6.96 * 10⁵ km

1.9 * 10⁻⁴ mm = 0.00019 mm

Numbers that are either very large or very small can be written in an alternate form by expressing them in the method of scientific notation. Here a given number between 1 and 10 is multiplied by the power of 10. Specifically, the number is expressed in two parts: Digits/Decimals + 10^power

Here:

Radius of the sun = 696,000 km

In scientific notation, radius = 6.96 * 10⁵ km

The measurements can also be converted from scientific notation to the regular form of decimals or whole numbers.

Here:

Radius of bacterial cell in scientific notation= 1.9 * 10⁻⁴ mm

Alternate form = 0.00019 mm
