To multiply numbers in scientific notation, we multiply the coefficients and add the exponents.
In this case, we have (5.5 × 10^4) multiplied by (2.2 × 10^(-8)).
Multiplying the coefficients, we get (5.5 × 2.2) = 12.1.
Adding the exponents, we get (10^4 + 10^(-8)) = 10^4.
Therefore, the answer in scientific notation is 12.1 × 10^(-4).
The correct answer is 1.21×10^−4.

To multiply two numbers in scientific notation, you multiply the coefficients and add the exponents of the powers of 10.
So, the correct response is: Multiply the coefficients and add the exponents of the powers of 10.
To multiply two numbers in scientific notation, you need to multiply their coefficients and add their exponents.
In this case, the coefficient of 5.5×10^4 is 5.5, and the exponent is 4. The coefficient of 2.2×10^-8 is 2.2, and the exponent is -8.
To calculate the product of the coefficients, multiply 5.5 by 2.2:
5.5 × 2.2 = 12.1
To calculate the exponent of the product, add the exponents:
4 + (-8) = -4
So, the answer is 12.1×10^(-4).
