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

To multiply these two numbers, you add the exponents and multiply the coefficients:

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

= (8.03 X 2.56) X (10^-8 X 10^-2)

= 20.5768 X 10^(-8-2)

= 20.5768 X 10^-10

= 2.05768 X 10^-9

To multiply two numbers in scientific notation, you need to multiply the decimal parts and add the exponents.

(8.03 × 10^-8) × (2.56 × 10^-2)

Multiply the decimal parts: 8.03 × 2.56 = 20.5568

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

Therefore, the answer is 20.5568 × 10^-10 in scientific notation.

To multiply two numbers expressed in scientific notation, you need to multiply the two numerical parts and then multiply the powers of 10.

Let's calculate (8.03 X 10^-8) X (2.56 X 10^-2) step by step:

1. Multiply the numerical parts:
8.03 X 2.56 = 20.5568

2. Multiply the powers of 10:
10^-8 X 10^-2 = 10^(-8-2) = 10^-10

3. Combine the numerical part and the power of 10:
20.5568 X 10^-10

So, the result is 20.5568 X 10^-10, or more commonly expressed as 2.05568 X 10^-9.
