What is 5.5•10^4 multiplied by 2.2•10^-8. Write in scientific notation.

Answer 1

The calculation is:

(5.5 • 10^4) * (2.2 • 10^-8)

To multiply numbers written in scientific notation, we multiply the coefficients and add the exponents. The result is:

(5.5 * 2.2) • (10^4 * 10^-8) = 12.1 • 10^-4 = 1.21 • 10^-3

Therefore, the answer in scientific notation is 1.21 • 10^-3.
