What is 5.5 × 10⁴ multiple by 2.2 × 10^-⁸? Write the answer in scientific notation.

Answer 1

To multiply these numbers, we can simply multiply the decimal parts (5.5 × 2.2) and add the exponents (10⁴ + (-⁸)).

5.5 × 2.2 = 12.1

10⁴ + (-⁸) = 10⁴ - 8 = 10⁻⁴

Therefore, the product of 5.5 × 10⁴ and 2.2 × 10^-⁸ in scientific notation is 12.1 × 10⁻⁴.
