Answer 1

To multiply two numbers written in scientific notation, you need to multiply their coefficients and then add their exponents.

(8.03 x 10^-8) x (2.56 x 10^-2)

Multiplying the coefficients: 8.03 x 2.56 = 20.5568

Adding the exponents: -8 + (-2) = -10

The final answer is 20.5568 x 10^-10.
