To multiply two numbers in scientific notation, you need to multiply their decimal parts and their exponent parts separately, and then combine them.
Given:
First number: 8.03 × 10^-8
Second number: 2.56 × 10^-2
Multiplying the decimal parts: 8.03 × 2.56 = 20.5568
Multiplying the exponent parts: 10^-8 × 10^-2 = 10^(-8-2) = 10^-10
Therefore, the result is 20.5568 × 10^-10.
In scientific notation, we typically express the decimal part as a number between 1 and 10, so we need to express 20.5568 as 2.05568 × 10.
The final answer in scientific notation is:
2.05568 × 10^(-10)
8.03x10^-8 x 2.56x10^-2=?
