Type the correct answer in the box.
scientists often deal with numbers that are either very large or very small. for example, 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, the radius of the sun is
× 10
kilometers.

in expanded notation, each bacterial cell is
millimeters wide.
