To find the product of 5.5×10^4 and 2.2×10^-8, you can apply the rules of multiplication for numbers in scientific notation.

Step 1: Multiply the numbers without the powers of 10. 5.5 multiplied by 2.2 equals 12.1.

Step 2: Multiply the powers of 10. Add the exponents to find the new exponent. 10^4 multiplied by 10^-8 equals 10^(4-8) which simplifies to 10^-4.

Step 3: Combine the result from step 1 with the result from step 2 to express the final answer in scientific notation. The answer is 12.1×10^-4.

So, the correct answer in scientific notation is 12.1×10^-4.

To multiply two numbers in scientific notation, you multiply the coefficients and add the exponents.

First, multiply the coefficients: 5.5 x 2.2 = 12.1.

Next, add the exponents: 10^4 x 10^-8 = 10^(-4+(-8)) = 10^(-12).

So, the answer in scientific notation is 12.1 x 10^-12.
