What is 5.5 Multiple 10-4 multiplied by 2.2 times 10-8?

Answer 1

To multiply numbers written in scientific notation, you multiply the numerical parts and add the exponents.

(5.5 × 10^(-4)) × (2.2 × 10^(-8)) = 5.5 × 2.2 × 10^(-4) × 10^(-8)

Multiplying the numerical parts: 5.5 × 2.2 = 12.1

Adding the exponents: 10^(-4) × 10^(-8) = 10^(-4+(-8)) = 10^(-12)

Therefore, the result is 12.1 × 10^(-12).
